If you do not have high demands on the accuracy of measurements, the very fact of determining the presence and excess of alcohol in the blood is important to you, you can consider an inexpensive model with a semiconductor sensor. Or a model without a mouthpiece. The latter have their advantages: they do not require searching and the cost of purchasing mouthpieces, and are easier to use.

It is worth paying attention to the operating temperature, whether it will suit your conditions. The frequency of calibration is also an important point; find out whether it will be possible to carry out the process without problems. Pay attention to the quality, size of the display and information displayed.

Last but not least is the design and dimensions of the device; it is always nicer to have a convenient thing that will please the eye. Enjoy the shopping!

On the way, he was stopped by traffic police officers and asked to breathe into their pipe. Their device showed nothing. We recommend purchasing.

What to look for when choosing

It's time to figure out how to choose a breathalyzer for personal use. We recommend paying attention to the following characteristics:

Device preparation time– the smaller it is, the faster the check will be.
Response time– how quickly the device produces results.
Measuring range.
Allowable error.
Working temperature– this indicator is especially important for residents of the northern regions.
Number of tests per battery charge - varies from 200 to 500 for different models.
Guarantee manufacturer.
Blowing method– with/without mouthpiece.
Indication battery charge.
Availability self-test systems and self-cleaning of the sensor.

Decoding the device readings

ppm(‰) is a thousandth of a percent. This unit is used in laboratories to determine the degree of intoxication.

A few simple examples will help you understand what your device shows:

0.5 liters of vodka contain 200 ml of pure alcohol, which corresponds to 2.5 ‰ in a man’s body;
a bottle of beer, a quarter liter, will show 0.16‰ on the measuring device;
a drink with a strength of up to 12% with a volume of 0.7 l will show 0.12‰.

Answers to popular questions

When choosing a breathalyzer, many questions arise. We will answer the most popular of them below.

How many ppm of alcohol is allowed for drivers in 2018 - 2019?

The answer to the question of how many ppm of alcohol is permissible for drivers in 2018–2019 is in the law, which came into force in 2013 and introduced acceptable levels of 0.16‰ when exhaled or 0.3‰ in the blood.

How long will it take for a breathalyzer to not show alcohol?

No less important is the question of how long the breathalyzer will not show alcohol. Due to the fact that alcohol does not disappear for a long time, it is advisable for motorists to know the time frame for removing alcohol from the body.

The table shows the approximate periods of elimination of 200 grams of alcohol:

What kind of breathalyzers does the traffic police use?

When purchasing a breathalyzer for personal use, you want to be sure that its readings in a critical situation will coincide with the data from the device of the traffic police inspector. Let's figure out what kind of breathalyzers the traffic police uses so as not to find yourself in an unpleasant situation.

Breathalyzers for traffic police officers – exclusively professional devices designed for repeated use throughout the day and having high accuracy of readings.

Now in Russia several models of devices are used to identify violators:

Breathalyzer Alcotest 6810 German made. Devices may have a printer or operate without one.
Device Alcotest 7410 plus. The mechanism operates in a temperature range of –5 – +45 degrees. The maximum error for such a breathalyzer is 5%.
Apparatus PRO-100 Combi. Such a device has excellent memory and is capable of storing up to 2000 previously obtained results.
Device LION (SD-400P). The technical characteristics of such a device are close to the characteristics of the PRO-100 Combi tester.
Canadian device Alert J4 Xec. The sensor is cleaned within 1 minute.
Device AKPE-01 M, operating on the principle of interaction of ethanol with the infrared radiation of the device.

Is it possible to fool a breathalyzer?

Breathalyzers work on the principle analysis of the presence of alcohol in exhaled air. Alcohol enters the air a person exhales from the lungs. But it gets into the lungs from the blood. Accordingly, the more alcohol in the blood, the more of it in the exhaled air.

That is, it doesn’t matter whether you drank the traditional way or took an alcohol enema - you will exhale the same amount of alcohol

There are legends that the breathalyzer is deceived by: chewing gum, chocolate, seeds, activated carbon, cigarettes, coffee, cinnamon, bay leaf, nutmeg, garlic or Anti-policeman. Is it so? Numerous folk experiments have shown that none of the listed methods does not work. And experts confirm that there are no products that can mask alcohol.

Breathalyzer for smartphone: should you trust it?

The breathalyzer for a smartphone is very compact, no larger than a standard flash card. The fact is that the device is not autonomous, and most of the functions that ensure operation are taken over by the smartphone. To use a breathalyzer you must install a special application, the settings of which indicate the age, gender, weight of the subject.

Practical experiments have confirmed the ability of smartphone breathalyzers to detect low alcohol content, which, in fact, is the defining criterion for a control breathalyzer.

Where can I buy?

Good and inexpensive models of portable breathalyzers are always on sale in these stores:

M Video.
DNS.
Yandex Market.

Drunk driving causes tens of thousands of accidents every year. A breathalyzer will help prevent you from driving in this state, as it will determine the level of alcohol in your blood with maximum accuracy. This device is actively used for personal purposes, by traffic police and in medicine. It can be professional and personal.

When choosing this device, keep the following in mind:

Sensor type. It is divided into semiconductor, electrochemical, spectrophotochemical. The first one is most often built into personal models, and the rest - into professional ones.
Error. Its level ranges from 1% to 20%. It is highest for devices with a semiconductor type sensor.
Air intake method. It is carried out by freely exhaling air into a special hole (mouthpiece-less method) and/or by placing a mouthpiece in the oral cavity. The latest devices are more expensive, but they are more accurate.
Functions. Breathalyzers may have useful options - time, temperature, stopwatch, alarm clock.
Range and units of measurement. It usually ranges from 0.00 to 5.00 mg/L. The higher this number, the more accurate the results will be. Alcohol concentration is indicated in % BAC, mg and ppm per 1 liter.

We studied the characteristics of more than 100 different models of breathalyzers in the categories “inexpensive”, “professional” and “personal”, selecting the 12 best from them. The choice was made taking into account all the above parameters, and user reviews were also taken into account.

The best of inexpensive breathalyzers: budget up to 1,500 rubles.

Such devices are usually offered by Chinese manufacturers. We are most often talking about conventional semiconductor models. The quality of their work is called into question by traffic police officers, and the results obtained through the use of inexpensive breathalyzers have no legal force.

When we are faced with the need to buy this or that product, which we have only heard about out of the corner of our ears, we begin hastily typing unfamiliar terms into search engines in order to understand “what it is and what it is eaten with,” so as not to be deceived once again by an unreliable seller.

Today we will try to answer one simple but frequently asked question: “Which sensor is better to buy a breathalyzer - electrochemical or semiconductor?” But before we give a short and monosyllabic answer, let’s at least figure out what it is "semiconductor sensor", and what is "electrochemical sensor".

Semiconductor sensors.

The principle of their operation is outrageously “simple” and without going into technical intricacies, the essence is this: the sensor is a small cylindrical metal heat-resistant shell. When alcohol vapors enter this sensor, their molecules react with oxygen, which in turn leads to an increase in the electrical conductivity of the sensor (with a high concentration of alcohol molecules, the conductivity correspondingly increases significantly). The resistance decreases and the electrical current passing through the sensor increases. This signal is sent to the converter, which is transmitted to the device display in the form of numbers (most often), or as a color indication. That's all.

What are the advantages and disadvantages? The price of breathalyzers with a semiconductor sensor is obviously lower, but the main drawback lies in the selectivity of the device to the composition of the exhaled breath, i.e. he may make a mistake and mistake other substances for alcohol vapor, which in their molecular structure resemble an alcohol molecule. We also take into account the increased measurement error (up to 20-25%), as well as the increased sensitivity of the sensor to frequent use. It is not recommended to use such devices more than 1-2 times a day to avoid damage to the sensor.

Electrochemical sensors

The physical composition of an electrochemical sensor is much more complex and we will not dwell on it, so as not to once again clutter your brain with unnecessary information. We only note that this sensor is more accurate, durable and more legible. The price of devices with an electrochemical sensor is higher, but as a rule, given the rare need for their repair, replacement, etc., the price is completely justified and in some cases is cheaper than semiconductor ones. So it's up to you and only you to decide :)

When choosing this device, keep the following in mind:

Sensor type. It is divided into semiconductor, electrochemical, spectrophotochemical. The first one is most often built into personal models, and the rest - into professional ones.
Error. Its level ranges from 1% to 20%. It is highest for devices with a semiconductor type sensor.
Air intake method. It is carried out by freely exhaling air into a special hole (mouthpiece-less method) and/or by placing a mouthpiece in the oral cavity. The latest devices are more expensive, but they are more accurate.
Functions. Breathalyzers may have useful options - time, temperature, stopwatch, alarm clock.
Range and units of measurement. It usually ranges from 0.00 to 5.00 mg/L. The higher this number, the more accurate the results will be. Alcohol concentration is indicated in % BAC, mg and ppm per 1 liter.

The best of inexpensive breathalyzers: budget up to 1,500 rubles.

Which brand of breathalyzer should I buy?

Dingo

A huge number of breathalyzers are produced under the Dingo brand. Some of them have a very low price tag. Others try to justify the high cost with a nice body and more accurate measurements. Be that as it may, almost all Dingo breathalyzers are designed for a long service life. And this is precisely what is most important - you don’t want to buy such a device every three or four years?

AlcoHunter

In fact, this brand belongs to an online store. On his site, he sells various breathalyzers from foreign and domestic manufacturers. But some time ago the company decided to brand third-party products, releasing them under its own brand. And these are not necessarily some kind of budget solutions. The company's assortment now includes professional models. They have an improved sensitivity sensor, and such breathalyzers also delight with their design, which inspires respect.

Dräger

Dräger is a family-owned company founded back in 1889. The company began its history with a modest company manufacturing pressure-reducing valves for cylinders used for dispensing beer. Subsequently, the company produced a wide variety of equipment needed for a comfortable life. For example, in 1924, a breathing apparatus began to roll off the assembly line, and two years later an anesthesia device was developed. Well, the first breathalyzers were created by the company in 1953. Since then, these devices have been regularly improved. Now Dräger products can safely be called professional, their readings are so accurate.

The SITITEK brand belongs to a Russian distributor of various electronic products. For example, this company distributes very good robotic vacuum cleaners under its own brand. You can also find breathalyzers in its assortment. These devices may be similar to a digital voice recorder or a cell phone. Such devices have a monochrome screen on which the breathalyzer readings are displayed. There are no professional models in the SITITEK range yet.

The best breathalyzers

TIGON M-3001

A kind of flagship product of the TIGON company. It costs a lot of money, but it provides very accurate measurement results. The error does not exceed 0.05 g/l. The device also features quick preparation for a new measurement - recovery takes less than seven seconds.

Advantages:

Able to work at almost any temperature;
It is small in size and weight;
Very low error;
The measuring range is very wide;
The active measurement mode is supplemented with screening;
There is a high-quality electrochemical sensor;
Powered by its own lithium-ion battery;
Up to 50 thousand tests are stored in memory;
The kit includes a car adapter and a network adapter.

Flaws:

Very high price;
Replaceable mouthpieces are used.

Reviews of TIGON M-3001 show that many medical institutions are choosing this device. Buyers like the inclusion of five dozen disposable mouthpieces in the kit. Also, everyone likes the fact that the manufacturer has added not only a network adapter, but also a car adapter. This allows you to charge the breathalyzer not only at home, but also in the car. But this action is rarely required, since the capacity of the battery built into the device reaches an impressive 2200 mAh.

A professional device produced by a company with a long history. It is often purchased by medical institutions, as well as the state road safety inspection. The device easily understands the vapor from heart drops, distinguishing them from real alcohol. In this case, the device is supplied with a printer, which will document the readings on paper.

Advantages:

There is a package that includes a printer;
Very small size and weight;
Simplified management;
Accurate determination of ethanol residues in human breath;
The device turned out to be very reliable;
Functions even at sub-zero temperatures;
The memory is enough for 5000 tests.

Flaws:

Overly inflated price tag.

Reviews of the Drager Alcotest 7510 show that it is impossible to find fault with the functionality of this device. It does its job virtually perfectly. High accuracy is complemented here by the possibility of use in conjunction with a printer. The latter connects wirelessly - information is transmitted to it using an infrared port.

Another professional breathalyzer produced by a renowned company. It features an ergonomic body design and the ability to synchronize with a printer. Additional cables are not required to print out measurements, which is thanks to the optical data transfer interface.

Advantages:

Rich equipment;
A printer is included;
Minimum wires;
Minimum measurement error;
Available in the list of recommendations for use by traffic police inspectors;
The device turned out to be very reliable.

Flaws:

Many motorists will definitely not be able to afford it;
Replaceable mouthpieces won't appeal to everyone.

Reviews of the Drager Alcotest 7510 indicate that some people do not like the shape of the mouthpieces that come with it. By the way, they are replaceable - buying one piece will cost about 10-12 rubles. As for the characteristics of the breathalyzer itself, not a single buyer can find fault with them. It seems that the manufacturer managed to create an ideal. It's a pity that the price of this device is very steep.

One of those breathalyzers that are commonly called budget. This model has two modest monochrome displays. They display the current time, ambient temperature, and blood alcohol level readings. The device can also be used as an alarm clock and timer. As expected, the device provides measurement results in grams per liter and ppm. The breathalyzer also warns a person with the words “Caution” and “Danger”.

Advantages:

Functions without replaceable mouthpieces;
Very low cost;
Availability of alarm clock, timer and clock;
The error is not the highest (0.1 ppm);
The result is displayed in just two seconds.

Flaws:

Battery operated;
After a long break, three measurements have low accuracy.

Reviews of SITITEK Pro2 indicate that the device works very strangely. If it has not been used for a long time, then the first three measurements are extremely inaccurate. Only the fourth result is correct. You definitely need to remember this at the moment when you decide to drink alcohol and then get behind the wheel. Another oddity is the use of two types of batteries at once. The breathalyzer itself operates using AAA batteries, while the clock, alarm clock and timer require an AG13 battery.

It's hard to call this model inexpensive. But it is much cheaper than many other professional solutions. The measurement accuracy here is an order of magnitude higher when comparing the device with budget analogues. Also, the buyer should like the interface that is displayed on the display. The creators have used improved calibration that eliminates the influence of the environment on the measurement result - this is also a very important advantage of the device over its competitors.

Advantages:

Easy to use;
The price is not too high;
High quality workmanship;
Capable of working for many years.

Flaws:

Restoring the sensor after measurement takes a long time.

Reviews of AlcoHunter Professional+ show that it is difficult to recommend something better to the average driver. Of course, some of the devices we mentioned offer even more accurate readings and also have additional functions. But they also cost much more, which makes their purchase unaffordable. Well, this model is optimal in terms of quality and price ratio, which is good news.

Which breathalyzer to choose

1. Today you got acquainted with five breathalyzers, which are the best among those available on the Russian market. Choosing one of them is not as difficult as it seems. Just focus on the amount of money you have. Not ready to pay more than two or three thousand rubles? Then the best candidate is SITITEK Pro2. Think it's better to pay a little more but get more accurate measurements? Then look for AlcoHunter Professional+ in the store.

2. The remaining devices considered are primarily intended for professional use. This is proven by the fact that they are all capable of interacting with a pocket printer. And if the TIGON M-3001 costs relatively little if you buy it without a printing device, then purchasing a Drager Alcotest 7510 and 6810 will cost the same amount as a TV with a curved 4K screen!

All breathalyzers have a similar operating principle and design. Essentially, they are microcomputers. The main elements are:

a housing with a hole or a special device for exhaling air;
sensor (sensor);
microprocessor for processing test results;
display with a system for issuing digital test results.

The operating principle of all types of breathalyzers is also the same:

exhalation of air through a special hole;
interaction of air with the sensor;
receiving the induced electrical signal by the microprocessor;
processing of results;
displaying test results on the device display.

The electrical signal is generated differently in different types of breathalyzers.

Based on performance and technical capabilities, breathalyzers produced today are divided into 4 main types:

Individual. They are used for short-term use for self-monitoring of one person (usually the owner), designed for 1-2 tests per day.
Professional. They are called breathalyzers and are intended for frequent use (up to 150-350 times a day). They have high measurement accuracy, the ability to connect a printer to display the result on paper, and require calibration 1-2 times a year.
Special. For a small number of inspections (5-30 per day), used in small enterprises.
Club. The middle option between special and professional. They got their name because of their use in clubs, cafes, restaurants and other establishments of this type.

Before choosing a breathalyzer, you need to decide for what purposes it will be intended. The device is purchased for personal use or for use in an enterprise. You should also be sure to consider which tester functionality is needed in a particular case.

Today there are a large number of devices from various manufacturers on the market. They have different characteristics and parameters, so you can choose any one according to your needs and financial capabilities.

Types of breathalyzers

One of the most important parameters of the tester is the permissible frequency of its use over a certain period of time. Based on this criterion, breathalyzers are classified into:

individual;
special;
professional.

An individual breathalyzer can perform up to five tests per day, a special one - up to fifty, and professional devices, which make up the largest group on the market - more than fifty tests per day.

Individual testers are in most cases purchased for personal use. Special - for checking a certain number of people. For example, such breathalyzers can be used to test taxi or bus drivers before departures.

Professional testers are called breathalyzers and are used by traffic police traffic inspectors, police officers at public events, and security guards at checkpoints of large enterprises.

There are other classifications. Based on the type of sensor used, there are:

semiconductor;
electrochemical;
photometric.

Some testers use a system to protect against attempts to deceive. If a person tries to outwit the device in any way, he reacts to this with a light or sound signal.

Even the highest quality and most expensive device shows less and less accurate results over time. Each device is designed for a certain number of uses, and with use, the error in measurements increases more and more.

How does a breathalyzer work?

The device is designed to determine the alcohol content in exhaled air. Electrochemical and semiconductor breathalyzers are considered the most accurate and widespread today. The principle of operation of the device is based on changes in sensor indicators under the influence of alcohol vapor.

Testing consists of a person exhaling air into a tube or a special hole, and the sensor used in this device changes the readings if it detects the presence of ethyl alcohol.

Types and features of sensors

Devices with semiconductor sensors use the principle of changing the resistance of a semiconductor under the influence of alcohol vapor. They have a number of advantages:

ease of use;
relatively high accuracy;
speed of measurements.

Breathalyzers with electrochemical sensors use special chemical compounds that react only to ethanol. These devices are characterized by very high measurement accuracy and low energy consumption.

Testers with photometric sensors are the most accurate; their work is based on the fact that alcohol vapor absorbs infrared light. The higher the absorption coefficient, the more alcohol vapor in the exhaled air. These testers are overly sensitive to environmental factors, so they cannot be used outdoors.

In order for the breathalyzer to show accurate results, it must be periodically calibrated. Semiconductor sensors require the most frequent adjustments. For electrochemical devices, reconciliation can be carried out approximately once a year.

The error and quality of measurements depend both on the type of sensor and on the amount of alcohol vapor in the air being tested. Semiconductor sensors have an error of up to 20%, and electrochemical sensors - up to 10%. It should be noted that the less alcohol in the exhaled air, the less accurate the device readings will be. If a person has drunk a little beer, it will be more difficult for the device to determine intoxication, since there will be little alcohol vapor. It’s another matter if the subject drank a bottle of vodka before the test, in which case the readings of the presence and concentration of vapors will be more accurate.

When deciding which tester is best to buy, you should listen to the advice of experts. They recommend choosing a device based on the following points:

purpose of the device, functionality;
price;
expected frequency of use;
device maintenance.

First of all, it is necessary to determine whether the breathalyzer will be an ordinary household device for personal use, or whether it is intended to be used, for example, at an enterprise to examine employees. In the latter case, you need to buy a certified breathalyzer. Testimony from certified devices has official force and can serve as evidence in proceedings, for example, in court. Based on the testimony of a certified tester, an official document can be issued confirming the state of alcohol intoxication or crystal sobriety.

The accuracy of household or personal breathalyzers is not as high as that of professional breathalyzers, however, even an inexpensive home device will help determine whether a person has consumed alcohol within the last few hours.

The price of a breathalyzer in the vast majority of cases determines its quality. In any case, it is clear that cheap devices are not subject to constant reusable use, they lose accuracy faster and are more likely to become unusable. When choosing a device, even for personal use, it is better to pay attention to products from reputable manufacturers with high ratings in numerous reviews. It makes sense to listen to the reviews of experienced car owners.

Among the manufacturers of testers, the top best in 2017, and at the same time not very expensive, include companies such as Drager Alcotest, Drivesafe. One of the best devices on the list for car enthusiasts, according to reviews, is the “Dingo A-070” from the manufacturer “Dingo”.

The most inexpensive models can be used no more than once or twice a week. Expensive professional breathalyzers can accurately test hundreds of people every day.

As for service, it is better to find out in advance how the sensor can be changed in the model you like, and how often it needs to be calibrated and tested. In expensive breathalyzers, you can change the sensor yourself, but a cheap one will have to be taken to a service center. It is recommended to find out in advance whether the purchased model is serviced in the area where you live, what its price is, and whether it is possible to purchase a replacement sensor.

When choosing a breathalyzer, everyone proceeds from their own needs, tasks and financial capabilities, so it is almost impossible to give universal advice.

Which breathalyzer to choose

vyboroved.ru

Why are breathalyzers with an electrochemical touch sensor better than semiconductor devices?

We often get asked the question: why is an electrochemical alcohol sensor better than a semiconductor one? What difference does it make which sensor is installed in the breathalyzer? Why change a device with a semiconductor sensor to a device with an electrochemical one?

In the description of breathalyzers and breathalyzers you can find the following characteristics: high accuracy and selectivity. These characteristics are ensured by the use of electrochemical alcohol sensors, which replaced semiconductor ones. The type of sensor must be indicated in the technical specifications of the device, and if this is not the case, then you should ask the seller yourself which sensor is installed in the device. Otherwise, you risk buying an outdated semiconductor device.

Operating principle of an electrochemical alcohol sensor.

The operating principle of the electrochemical alcohol sensor is based on the electrochemical reaction of ethanol oxidation to acetic acid, which occurs in the so-called “fuel cell”:

C 2 H 5 OH + O 2 → C 2 H 4 O 2 + H 2 O

The electrochemical ethanol sensor consists of two active platinum surfaces, on which a specially selected catalyst is deposited, in the presence of which the bonds in ethanol molecules are weakened. Between the platinum surfaces there is a porous substrate impregnated with electrolyte. A polymer membrane applied to one of the plastic surfaces serves as a physical barrier that regulates the intensity of the reaction on the active catalytic surface. When air containing ethanol vapor is blown through the body of the sensor cell, positively charged hydrogen ions H+ are torn off from ethanol molecules near the active catalytic surface and free electrons are released. H+ ions migrate through the electrolyte, reaching the second surface, where they form water by contacting oxygen in the air. Thus, a negative charge is formed on the upper surface due to the excess of electrons, and a positive charge on the lower surface. Being included in an electrical circuit, the sensor cell creates a current in the circuit, the strength of which at the moment of the peak will be proportional to the number of free charges formed on the surfaces and, consequently, to the number of ethanol molecules that have reacted near the active catalytic surface.

That is why the electrochemical sensor provides high accuracy and, thanks to the correct choice of catalyst, and close to absolute selectivity to ethanol.

Due to its technical features, the electrochemical touch sensor allows you to integrate an intake system into the device - this is a micro pump that captures air from the depths of the lungs at the end of exhalation (alveolar air) and delivers it to the touch sensor for analysis. The use of an intake system significantly increases the reliability of the measurement.

Service life of the electrochemical alcohol sensor.

The average service life of an electrochemical touch sensor is significantly higher than a semiconductor sensor and can be up to 5 years, of course, subject to proper operation. At the same time, devices with an electrochemical touch sensor do not require adjustment once every 2 months, like semiconductor sensors (a feature of semiconductor sensors is a constant and gradual change in the sensor parameters, even if the device has not been used). Personal breathalyzers with an electrochemical touch sensor require adjustment once every six months, and professional breathalyzers (alcometers) with an electrochemical sensor - once a year before verification as necessary.

Which breathalyzer to choose: semiconductor or electrochemical?

In the production of breathalyzers, there are several types and devices are divided according to purpose:

professional;
personal;
specialized.

The purpose of the device depends on the requirements

Let's consider the selection criteria:

Breathalyzer accuracy class. For personal use, choose low-end models. In surveys, law enforcement services use more accurate sensors. The choice of internal device of the tester depends on the accuracy. Mass inspections require increased measurement accuracy and speed of device preparation. If for personal use the devices are inexpensive and allow up to 4 tests per day, then professional breathalyzers can be used up to 30 times a day. The pause between checks of professional devices is no more than 10 seconds.
Performance speed. In home use, a couple of extra minutes is not important. When used in enterprises, several people are checked at checkpoints during these minutes. For these purposes, specialized instruments are used that have low pause values between measurements and measurement accuracy.
Terms of Use. Sobriety testing of drivers takes place in difficult conditions for a breathalyzer. Temperature changes during measurements at different times of the year affect the test results. Factors of the chemical composition of the air being tested are also taken into account. Exhaled vapor has a heavy chemical composition, which can cause the sensitive sensor of the breathalyzer to malfunction. This composition is found in cigarette smoke or exhaust gases.
Ability to work with peripheral equipment. To print the test results, traffic police officers use the built-in printer in the breathalyzer. The possibility of connecting via ports to a personal computer to save a database of checks is being considered.
Display information. Selecting the display of device information for easy analysis of results. The digital display shows concentration values in percent, ppm or mg/l. The simplest devices have two indicator diodes - green is positive, red is the set value is exceeded. Laws are changing and a device set to one sensitivity threshold becomes unsuitable for determining intoxication.
Device dimensions. An important characteristic is the dimensions of the breathalyzer used. The device, which fits in your pocket, looks more compact and fits comfortably in your hand when checking.

Additional selection criteria are the cost of the product, appearance and maintainability. When a breathalyzer element fails, it is more practical to replace a separate part than to buy a new device. When purchasing a device, the possibility of replacing the mouthpiece and sensor is taken into account. The presence of additional sensors will affect the choice of model. Some models are equipped with an air volume sensor.

The volume sensor eliminates the error from incorrect exhalation that has interruptions. Measurements are carried out automatically when the set volume is reached and the accuracy is calculated for a constant vapor value. A built-in pump is used in conjunction with a volume sensor. A pump is used to draw air from the depths of the lungs, which increases the accuracy of the tested ethanol concentration.

Based on the type of sensitive element, breathalyzers are divided into:

photometric;
semiconductor;
electrochemical.

The sensitive element of a photometric device works on the principle of capturing a deflected beam of light passing through the air being tested. Breathalyzers require certain operating conditions. They have measurement errors if temperature conditions are not observed. The cost of such devices is quite high and they are not widely used. They are the most accurate instruments and most models are made of a stationary type.

As the service life increases, the photometric device does not reduce its performance. The distinctive feature of a semiconductor device and an electrochemical one is due to the loss of its precision properties depending on the frequency of use. Semiconductor products have a smaller measurement margin than electrochemical products.

The mouthpiece may have a saliva filter and a check valve. This prevents saliva from entering the measurement chamber and prevents air from being inhaled. Each breathalyzer used undergoes periodic verification and calibration. The verification periods are established by the manufacturer and are indicated in the product passport. Semiconductor device and electrochemical have found application in personal purposes and professional testing. Let's take a closer look at each type of device.

The sensor of a semiconductor device is a semiconductor sensing element. During testing, the sensor heats up to a temperature of about 100 degrees. Ethanol vapors, burning on the surface, concentrate and change the conductivity of the sensor. The changed conductivity is recorded by the measuring circuit and converted into a digital form that is accessible to perception. Heating of the sensor is the most noticeable drawback of such devices. Tin oxide is used as the sensor material.

Heating makes the device more demanding of ambient temperature and humidity. The accuracy of such a product allows an error of up to 20 percent. The device's sensor is sensitive to the chemical composition of exhaled air. Smoking a cigarette before the examination will significantly distort the results and may damage the sensor. Polluted ambient air and high humidity will introduce some error in the readings.

The operation of electrochemical testers is based on the use of the property of a catalyst to release free electrons under the influence of ethanol molecules. The sensor is an anode coated with a catalyst. When alcohol vapor is deposited onto the catalyst, electrons are released. Electrons are captured by the conversion circuit and translated into information on the device screen. Such a sensor does not react to other vapor inclusions. Thus, high measurement accuracy is achieved.

The sensor does not require heating of the sensitive element and preparation for operation takes a matter of seconds. The influence of ambient temperature is minimal. The design of the sensor allows the use of a built-in pump. The pump is used to improve measurement accuracy. The breathalyzer is serviceable and, if it breaks down, allows you to replace individual elements, which will save the cost of a new purchase.

Comparative features of devices

Comparative analysis of semiconductor breathalyzer (PA) and electrochemical (EA):

Verification of PA devices is every 6 months - EA after 12 months.
The influence of the chemical composition of exhaled air on the sensitive element of the first type of product is higher than on electrochemical sensors.
PA requires up to 5 minutes to prepare for work, EA is prepared in 10 seconds.
EAs have a built-in pump and volume sensor.
PAs operate with error at high and low ambient temperatures. In PA, accuracy depends on the chemical composition of the exhaled air.
EAs operate stably under difficult conditions. The devices are selective to ethanol and the readings do not depend on the gas content of the room.

Rules for error-free air intake

The result of the intoxication test depends on compliance with the rules for using the device. At home, for self-monitoring, the ppm level can be checked several times a day before driving. Our own device allows us to carry out measurements under standard conditions.

In professional instruments, during a roadside inspection, no one will measure ppm again. In order not to waste time on a trip to a narcologist, it is better to exclude the error of testing on a breathalyzer. Here are a number of recommendations for measuring ethanol concentration in exhaled air:

Each device has a measurement error and this must be taken into account during the examination by traffic police officers.

Digital breathalyzer

The main difference between a digital breathalyzer is its very accurate readings. Another feature of such devices is that they can process large amounts of data and are designed for frequent use. It is not surprising that the breathalyzers used by the traffic police are of this particular group. But buying a digital breathalyzer for home use is not practical, the reason for this is the high price.

Professional breathalyzer

A professional breathalyzer, like a digital one, usually serves to test a large number of people (up to 70,000 people per year). Often such breathalyzers are equipped with printers for printing results. An example is a high-precision professional digital breathalyzer Draeger Alcotest 6810 (without printer), the price of which is 35 thousand rubles.

Personal breathalyzer

This group of breathalyzers is ideal for personal use. As a rule, the more expensive the breathalyzer, the more durable its sensor. For example, a cheap breathalyzer (600-700 rubles) requires very careful handling and cannot be repaired if it breaks. And the breathalyzer costs 4 thousand. rubles can be used every day without fear.

Currently, repairs of breathalyzers, as well as replacement of sensors, are available for large cities. A special feature of more expensive models is that you can replace the breathalyzer sensor yourself without contacting specialists.

When choosing a breathalyzer, pay attention to how the blowing will occur, with or without a mouthpiece.
More expensive models again stand out; they blow through a mouthpiece, which gives a more accurate result.

Read in the passport which sensor is in the breathalyzer (semiconductor or electrochemical). A semiconductor sensor is cheaper, but requires replacement from time to time (on average once every three months). The error of a breathalyzer with such a sensor is about 20%. The second group is with an electrochemical sensor:

Electrochemical breathalyzer

Devices with an electrochemical sensor are more expensive, about 8-9 thousand rubles. This device is particularly sensitive. Breathalyzer readings are highly accurate and fast, making it more effective than semiconductor devices. They usually do not require replacement of the sensor, only adjustment. The error of a breathalyzer with such a sensor is about 10%.

Breathalyzer calibration

The word “calibration” should mean setting up the breathalyzer sensor in a service center. If you do not do this, the breathalyzer readings will be less accurate each time. Semiconductor sensors are less wear-resistant than electrochemical ones. Typically, calibration of a breathalyzer is done after 200-300 blows, or when the device itself gives an error.

And again, simple personal semiconductor breathalyzers need to be taken to a service center for calibration, while more expensive ones can be made operational yourself by replacing the old sensor with a new one.

One of the best personal breathalyzers is the Dingo A-070 breathalyzer (price 3,500 rubles).

And finally, under no circumstances should you drive drunk; you endanger not only yourself, but also those around you.

Recently, breathalyzers and breathalyzers are gaining more and more popularity. These devices are now quite common and the buyer cannot always make an adequate choice. The first thing anyone who wants to buy a breathalyzer should know is the principle of operation. The most important thing in any alcohol meter is the accuracy of the measurement.

After all, you must agree, why have a device whose main purpose is to measure the degree of intoxication when it cannot determine it? The accuracy of the readings of any meter depends on the measurement itself and the accuracy of the device. The accuracy of the device itself depends on the accuracy of the process and its constituent elements. The measurement accuracy on some devices is reduced to an absolute value by establishing inhalation control and installing a “suction mechanism”. The first controls the exhalation volume for sufficiency. Secondly, it makes a fence practically from a person’s lungs.

If we talk about the accuracy of technology and elements, then to simplify it we can reduce everything to a measuring head. It is about this and why it is better to buy an electrochemical breathalyzer that we will discuss further. All alcohol meters can be divided into two types depending on the measuring element - semiconductor and electrochemical. The difference in these devices is approximately the same as the difference in a breathalyzer and a breathalyzer. The measurement accuracy of a semiconductor device is around 20%, and that of an electrochemical device is 10%. Of course, in every group there are exceptions, both positive and negative. It's all about technology. In a semiconductor device, the result of exhalation is reduced to an increase in the resistance of the circuit (heating of the element), which gives a large error. In electrochemical - to close the circuit and increase the voltage. The second method is more accurate due to the fact that the elements themselves are more sensitive and the chemical reaction takes place, albeit with small doses. It is worth noting that due to the very nature of the process, electrochemical meters have the property of “selectivity”, i.e. react only to alcohol.

If you have a choice about which breathalyzer to buy, then the best solution would be to buy an electrochemical breathalyzer. And it's not just about the precision laid down at the factory. The fact is that semiconductor devices constantly lose accuracy and often (every couple of months) need to be calibrated. As a result, you can buy a device that has already lost completely its accuracy in the store. Also note that for the device to be “legal” it must be calibrated by specialized organizations or their representatives. Alcohol meters based on an electrochemical reaction are a new type of device that will not let you down at the right time.

Types of breathalyzers

If you figure out how to choose the right breathalyzer, the main indicator is the frequency of use. Thus, devices that can conduct up to 5 tests per day are individual, up to 50 are special, and if this figure is above 50, then these are professional breathalyzers.

But the name “professional” does not distinguish these devices from the other two in terms of measurement quality. When answering the question of how to choose a breathalyzer, reviews are also of great importance, since active users immediately provide all the information about a particular device. Let us consider more specifically the types of these devices and their distinctive features.

Personal breathalyzers are primarily designed for self-monitoring. They may also be used in rare cases to test employees. On the market you can find individual devices of various colors and shapes. They also differ in the functions they perform. If you can’t decide how to choose a breathalyzer for yourself, then just ask the seller about this type of device - it will definitely suit you.

Special breathalyzers provide the opportunity to test more people per unit of time than individual ones. For example, they are used to control a group of drivers before setting off on a trip.

The largest among breathalyzers is the professional group. They are installed in places of leisure and recreation, at checkpoints. Professional breathalyzers make it possible to conduct even stream testing, for example, at public events.

Breathalyzers are further classified:

— by type of sensor used:

semiconductor;
photometric;
electrochemical.

- by type of sample collection:

mouthless;
mouthpiece

- according to the result indication:

switch;
digital;
LED

Some breathalyzer models use a deception detection system. It detects a person’s attempt to influence the result and emits a sound or light signal.

With prolonged use of any breathalyzer, the accuracy of measurements decreases due to loss of sensitivity of the sensor. In order to avoid incorrect readings, these devices are tested and calibrated. And although some manufacturers provide up to 5000 measurements, after 4000 the results are given with a large error. The calibration of the breathalyzer itself is carried out using special equipment, blowing air with a certain percentage of alcohol and the desired temperature.

Let's figure out how to choose a breathalyzer and in what price category it should be.

Principle of operation

A breathalyzer is a device that determines the percentage of alcohol in exhaled air. The most important element is the sensor. As mentioned earlier, it can be of three types. Nowadays, semiconductor and electrochemical sensors are most often used. They allow you to make the most accurate measurements and can withstand long-term loads. When deciding which breathalyzer to choose, be sure to pay attention to the type of sensor.

The principle of operation of a breathalyzer is quite simple. It consists of changing the parameters of the sensor when exposed to alcohol vapor. The person being tested blows air into the device through a mouthpiece or hole with a certain force and in the volume required for testing. Then the mixture moves through the tube into the reaction chamber where the sensor is located.

When ethyl alcohol comes into contact with it, the readings of electrical resistance, light absorption or reaction with a special substance change depending on the percentage of it in the exhaled air. Next, the processor processes the indicators and displays them in a human-readable form. In some models you can find additional functions in the form of a sound and light signal.

Proper testing

When deciding how to choose a breathalyzer for your home, the first thing you need to know is that for each person the indicators are purely individual. It all depends on the metabolic rate, weight and lifestyle of the subject. For example, if you take two people weighing 50 kg and 150 kg, then a dose of alcohol of 100 grams will last a long time for the first, and the breathalyzer may even show a zero value for the second.

Never test immediately after drinking alcohol. Firstly, it has not yet entered the blood, and the result will be false. Secondly, there is a high probability of “burning” the sensor with a high concentration of alcohol that still remains in the oral cavity.

Accuracy and Calibration

Before choosing a breathalyzer, it is worth understanding the errors. They directly depend on the type of sensor. Thus, semiconductors have an error of 20%, and sensor and photometric ones have an error of up to 10%.

It is also worth saying that the error depends on the vapor concentration. So, if it is small, then the exact value will be difficult to determine. If there is a high concentration of alcohol in the exhaled air, the indicator will be more accurate.

Main selection criteria

Before choosing a breathalyzer, you must decide on its operating conditions, the number of tests per unit of time and the accuracy of the readings. Let's look at them in more detail.

Types of sensors and their features

As already mentioned, there are three types of sensors:

Semiconductor. The measurement is made by changing the resistance of the semiconductor. Its features are: short response time, ease of use, frequent calibration due to changes in sensor properties, high accuracy.
Electrochemical. Here the measurement process is carried out using a special reagent that can only interact with alcohol. Their features are: high accuracy of indicators, low energy consumption, the ability to carry out calibration only once a year, and response only to alcohol vapor.
Photometric. These sensors use the absorption coefficient of infrared light by alcohol vapor. Among the features are quick readiness for work (2-5 seconds), high accuracy of readings due to the sensitivity of the sensor. But a breathalyzer with a photometric sensor can only be used in laboratory conditions due to the high dependence of the indicators on the ambient temperature.

Testing Methods

When figuring out how to choose a breathalyzer, you must definitely mention the testing methods and their features. So, they are contact and non-contact.

Non-contact testing is quite common among home models. This method is also very economical and simple. But non-contact testing significantly distorts the results, since they depend on wind strength, the presence of various impurities in the air, etc.

The contact method is more accurate due to the precise contact of exhaled air with the sensor. But it can also carry droplets of saliva, which significantly reduces the accuracy of the results.

Additional features of breathalyzers

Also, before choosing a breathalyzer or breathalyzer (another name for the device), you must know the additional capabilities of the device. So, in some models you can find the “anti-cheat” function. It gives a characteristic sound signal if the subject tries to imitate exhalation. Additionally, you can purchase a device that has a memory function. This is very important if you create a schedule or compare data with the testimony of traffic police officers.

Computer compatibility and self-calibration may also be present in breathalyzers. This makes it possible to be more confident in the accuracy of the device and save data on a computer for later printing.

Conclusion

Summing up the consideration of the question “how to choose a breathalyzer for yourself?”, we can highlight several main points.

First, be sure to decide for what purposes it will be used (for self-testing or for checking workers) and how many checks need to be carried out per day.

Second, pay attention to the type of sensor and the method for displaying results. It is recommended to choose breathalyzers with photometric and electrochemical sensors, as they have a very low error.

Third, decide on the additional capabilities of the breathalyzer. Do not forget that the cost of the device directly depends on this.
