How We Decided

We listed only breathalyzers that were highly accurate due to advanced, professional-grade technology that could give you consistent reading over time (some are even DOT or NHTSA certified). We also focused on ease of use and how the BAC information was transmitted. Some of the breathalyzers display test results on their own screen, while others transmit the information to your smartphone via a dedicated app.

We also considered battery life, which is vital when working with any type of technology. While most of the breathalyzers on the list run on replaceable batteries (AA and AAA), there is some that include a rechargeable battery too.

The last thing we looked at was any additional features that could help make your life easier and safer, like Bluetooth compatibility and the ability for the breathalyzer to call an Uber for you if your BAC registered too high to drive.

Another popular option that just missed our list is the AlcoMate Premium AL7000 Alcohol Tester. The AL7000 Professional Breathalyzer uses oxide semiconductor alcohol sensor modules in combination with PRISM Technology. The AlcoMate comes with a one-year warranty and combines professional reliability with an extremely easy-to-use one-touch operation.

Breathalyzer Buying Guide

The Most Important Features to Consider

When choosing a breathalyzer, first and foremost, you have to focus on accuracy and ease of use. Once you’ve found one that will give accurate readings without a lot of effort, you can figure out which additional features, like the ability to call an Uber or tell you how long it will take for your BAC to return to 0. 00%, are important to you.

  1. Accuracy
    Perhaps the most important feature to consider when choosing a breathalyzer is its level of accuracy. Many states are now using fuel cell sensor technology for breathalyzers, which can provide the most accurate readings. However, the influence of alcohol on these sensors can oftentimes result in inaccurate readings.
    • When you’re trusting a device to tell you what your blood alcohol content is, you want to make sure that it’s giving you correct and consistent readings. Nobody appreciates false positives that detect a false blood alcohol level.
    • Moreover, to ensure that you’re compliant with the law, an accurate breathalyzer is essential for knowing when you reach or exceed the legal limit. By using an accurate breathalyzer, you’ll stay within legal limits.
    • Choose a breathalyzer that’s gone through rigorous testing to ensure accurate results. While there are options for a cheap breathalyzer, it may not be as reliable or precise as an expensive breathalyzer. But, there are personal breathalyzers available at reasonable prices that are still accurate.
    • You can also test the breathalyzer on your own by using it when there’s no alcohol in your system to see if it gives you a 0.00 result consistently to determine if it’s an accurate device.
  2. Ease of use
    It’s also essential to consider how easy the breathalyzer is to use. With features such as fuel cell technology, the breathalyzer can accurately detect and measure the presence of alcohol in a user’s breath to deliver precise readings with maximum accuracy.
    • While complicated technology can present a problem even when alcohol isn’t involved, it can be almost impossible to figure out after a couple of cocktails. Since the accuracy of any breathalyzer relies on proper usage techniques, it’s important that the breathalyzer you choose is user-friendly.
    • Many of them operate with just one button and have an easy-to-read on screen display or the option to display your results on your smartphone.
    • Some digital breathalyzers even come with an LED display, making them easy to use in low-light environments. Users have praised the convenience and accuracy of these devices, according to online customer reviews.
    • In a professional setting, however, users need to be sure that the device provides a level of professional accuracy.
    • Others make sounds to alert you when your BAC is too high, which takes the guesswork out of figuring it out on your own.
  3. Size
    When it comes to breathalyzers, size does matter. Thanks to their portable designs and one-button operation or one-touch operation options, these devices can be carried around in a pocket or bag.
  4. You want something that’s convenient and small enough to slip into your pocket or your handbag when you’re out having a few drinks.
  5. If it’s too big, it will get left behind and, no matter how accurate it is, it’s useless if it’s at your house, so opt for types of breathalyzers with a sleek design.

Frequently Asked Questions (FAQs) |

Top Four Frequently Asked Questions

1. Why do I need a breath alcohol tester?

A Breathalyzer is a valuable purchase to ensure personal safety and the safety of others. An individual may purchase one for self-testing and monitoring to avoid the consequences of driving while intoxicated, or simply for a general understanding of how alcohol affects the body.

Since factors like weight, muscle mass, and recently consumed food or beverages all affect the measurement of person’s blood alcohol content (BAC), it’s impossible to accurately gauge intoxication level without a measurement tool like a breathalyzer. People are often enlightened when they measure their %BAC, particularly on different occasions after the same amount of alcohol is consumed.

2. What is the difference between the Personal and Professional Breathalyzer models you offer? Is a Professional Breathalyzer worth the extra money?

All breathalyzers sold at Breathalyzer. net are high quality and accurate products, and meet the standards of FDA 510(k) cleared devices, which means that the product has been deemed “safe and effective” for consumer use.

We’ve simplified the process of selecting a breathalyzer by categorizing all models into one of two categories: Personal Breathalyzers, which use semiconductor oxide sensors, and Professional Breathalyzers, such as BACtrack Mobile, BACtrack S80,BACtrack Trace, BACtrack S75, BACtrack Element, and Lifeloc FC-10, which use fuel cell sensors.

Professional Breathalyzers (which utilize fuel cell sensors) provide the following benefits over Personal Breathalyzers (which utilize semiconductor sensors):

  • They will not show a false positive for someone who is diabetic or on a low calorie diet. Semiconductor models will sometimes show a false positive result for these individuals. 
  • They provide more accurate and more consistent results as compared with semi-conductor models. For example, you are more likely to show the same test result when you test someone repeatedly in a very short period of time. In addition, they are more accurate at higher BAC concentrations, compared to semiconductor models, which often lose accuracy at higher BAC values. 
  • They can remain accurate for up to thousands of tests.
  • They provide more precise readings since %BAC readings are displayed to the thousandth decimal place (0.054%) versus to the hundredth decimal place (0.05%).

Breathalyzers that utilize fuel cell sensors typically sell for over $450; however, this technology is becoming more affordable with models like the BACtrack S80, BACtrack Mobile, BACtrack Trace, and BACtrack Element,, which are available for under $150.

3. Which breathalyzer model is right for me?

If you are interested in getting the highest level of accuracy in your readings, our recommendation is to spend the extra money on a Professional level breathalyzer that uses fuel cell sensor technology. These breathalyzers offer the same advanced technology used by law enforcement for preliminary screenings for a fraction of what they have previously cost. Law enforcement, substance abuse centers, clinics and businesses typically purchase these models, although they are often purchased for individual use too.

If you are more concerned with alcohol detection, the presence of alcohol versus the precise measurement of %BAC, a semiconductor oxide unit is likely satisfactory for your needs. These models are often used for self-testing or testing friends and family. The quality of these breathalyzers is far above novelty grade breathalyzers and they are both affordable and accurate.

4. What factors are important in choosing a breathalyzer?

Accuracy is likely the most important factor when making a breathalyzer purchase, so you should consider the Sensor Type – Semiconductor versus Fuel Cell. See question #3 above for information about the differences between these sensor types. Essentially, both options will provide accurate readings and the degree of accuracy will increase with the price.

FDA Approval is another important requirement to consider when choosing a breathalyzer. Every personal breathalyzer sold through meets the standards of a FDA 510(k) cleared device, which means the product has been deemed “safe and effective” for consumer use.

Breath Sample Collection is an essential factor, and critical to an accurate breathalyzer reading. While the use of mouthpieces is one element that aids in obtaining breath samples that exclude external air, other aids to accuracy are found in the actual product design. For instance, the miniature air pump featured in the BACtrack Mobile Breathalyzer, BACtrack S80, BACtrack Trace, and BACtrack Element allows for the highest level of precision in collecting a breath sample. During use, the user can actually feel the “click” of the pump collecting the breath sample.

Lastly, you should look at the Brand of Breathalyzer you are purchasing. The manufacturer should be reputable, in the business of selling breathalyzers, specifically, for an extended period of time and have the endorsement of professionals and press as a result of providing a quality and accurate product.

General Breathalyzer Questions

Common questions about Breathalyzers are listed below. If you don’t see an answer to your question, please feel free to contact us at [email protected] or 1-877-334-6876

How does a breathalyzer work? What types of technology do they employ?

Most breathalyzers use one of three technologies to detect Blood Alcohol Content or Blood Alcohol Concentration (BAC), which is the concentration of alcohol in a person’s blood: a semiconductor oxide sensor, a fuel cell sensor or a spectrophotometer, the latter being the technology used in large, table-top breathalyzers often found at police stations. offers breathalyzers with semiconductor oxide sensors and fuel-cell sensors.

Semiconductor oxide-based testers, such as the BACtrack S70, BACtrack S50 and the new BACtrack keychain breathalyzer are relatively new and very affordable. An ethanol-specific sensor is used to measure the subject’s BAC. Semiconductor oxide sensors offer many benefits, including low cost, low power consumption and small size.

Semiconductor oxide based testers require calibration service on a more frequent basis (every 300-400 tests or once a year) than fuel cell based testers (every 1,000 tests or once a year). When used for personal, home and low-volume professional testing, semiconductor oxide models have been proven to perform very well and provide accurate readings.

Fuel cell testers, such as the Lifeloc FC-10 Series, BACtrack Mobile, BACtrack S80 Pro,BACtrack Trace, and BACtrack Element, offer extremely high accuracy and sensitivity, in addition to being handheld and portable. In over 30 US states, roadside evidential testing is now permitted using testers using fuel cells. A fuel cell measures alcohol content by creating a chemical reaction that oxidizes the alcohol in the sample and produces an electrical current. The more alcohol that is oxidized, the greater the current. The current is measured to determine the subject’s BAC.

Spectrophotometer technology is used in large, table-top breathalyzers often found at police stations. Spectrophotometers work by identifying molecules based on the way they absorb infrared light. The level of ethanol in a sample is singled out and measured, and a subject’s alcohol level can then be determined. does not carry spectrophotometer testers.

What is %BAC?

Blood Alcohol Content or Blood Alcohol Concentration, abbreviated BAC, is the concentration of alcohol in a person’s blood. BAC is most commonly used as a metric of intoxication for legal or medical purposes, and it’s usually measured as mass per volume. For example, a BAC of 0.05% means 0.05 grams of alcohol per 100 grams of a person’s blood, or 0.5 grams of alcohol per 1000 grams of blood.

Factors that affect your BAC include the following:

  • Age – As you age, the intoxicating effects of alcohol become increasingly pronounced.
  • Gender – Alcohol is highly water soluble. Because women generally have lower water content in their bodies than men, they usually reach a higher BAC if they consume alcohol at a similar rate to their male counterparts, even if they are the same age and weight. Women also have a lower quantity of an enzyme in their stomachs that breaks down alcohol than men.
  • Rate of Consumption – The faster you consume alcohol, the faster your BAC will rise.
  • Drink Strength – The more alcohol a drink contains, the more will end up in your bloodstream.
  • Body Type – The more you weigh, the more water you tend have in your body, which has a diluting effect on the alcohol you consume. That’s why larger people usually require more drinks to “keep pace” with their smaller companions.
  • Fat/Muscle Content – Fatty tissue is low in water content and cannot absorb alcohol, and the alcohol must remain in the bloodstream until the liver can break it down. However, tissues that are higher in water content, such as muscle, do absorb alcohol. Hence BAC will usually be higher in the person with more body fat.
  • Metabolism – “Metabolic tolerance” varies from person to person and describes the rate at which alcohol is processed by the body.
  • Emotional State – Stress can cause your body to divert blood from your stomach and small intestines to your muscles, and slow down the rate of absorption of alcohol into your bloodstream. When you calm down and your blood flows normally again, you may experience a surge in your BAC.
  • Medications – Many medications react negatively with alcohol, including cold or allergy pills and prescription drugs. They can intensify the effects of alcohol and even endanger your health. If you are taking meds, check the product labels for alcohol warnings, or consult your doctor or pharmacist before you drink.
  • Food – If you drink alcohol on an empty stomach, your BAC will be higher than a person who has eaten before drinking. Food slows the absorption in your bloodstream by keeping the alcohol you consume in your stomach and for a longer period of time.
  • Carbonation – Carbonated drinks such as sparkling wine or champagne, or mixed drinks with sodas may increase the rate at which alcohol passes through your stomach and result in a higher BAC.
  • Diabetes – Alcohol can affect the glucose levels of people who have diabetes and cause hypoglycemia. Diabetics should consult their doctors about drinking alcohol and avoid drinking on an empty stomach.
  • Alcohol Intolerance – Alcohol may cause adverse reactions in some, including flushing of the skin, nasal congestion, elevated heart rate, and reduced blood pressure. According to the Mayo Clinic, alcohol intolerance is caused by a “genetic condition in which the body is unable to break down alcohol.

Am I safe to drive if my breathalyzer shows that I’m under the legal limit?

Absolutely not. Breathalyzers are for informational purposes only and there is no acceptable level of alcohol consumption that makes it safe to drive. Any alcohol that enters a person’s body can impair reflexes, motor skills, and cognitive abilities.

Is a person’s blood alcohol concentration (BAC) the only factor in determining whether or not a DUI is given?

No, the %BAC is not the only factor considered. Many people do not realize they can be charged with driving under the influence (DUI) or driving while intoxicated (DWI) even if their %BAC is under the legal limit. A person can be charged if they are at or over the “legal limit,” which is .08 %BAC in all 50 US States, or if they are “impaired to any degree,” regardless of the %BAC level.

Who invented the breathalyzer?

Though technologies for detecting alcohol vary, it’s widely accepted that Dr. Robert Borkenstein (1912-2002), a captain with the Indiana State Police and later a professor at the University of Indiana, is regarded as the first to create a device that measures a subject’s alcohol level based on a breath sample. In 1954, Borkenstein invented his breathalyzer, that used chemical oxidation and photometry to determine alcohol concentration. The invention of the breathalyzer provided law enforcement with a non-invasive test with immediate result reporting that can be used to determine an individual’s level of intoxication.

Is there any way to trick a breathalyzer?
This is a very popular question! Read our research on the topic to see how specific substances may affect the accuracy of a breathalyzer reading in our Breathalyzer Question of the Month section. While you’re there, read other interesting facts about breathalyzers, BAC, alcohol consumption, and more.

Is a breathalyzer eligible for my Flexible Spending Account (FSA) program?
Yes, in many cases they are eligible, however it really comes down to the FSA provider’s individual policy. Please check with your FSA provider for further details.

Breathalyzer Usage and Maintenance

How do I use my breath alcohol tester?

For most models, a user simply blows through the mouthpiece for 5 seconds. The blowing is similar to blowing out a candle and the user should blow evenly for the entire 5 seconds. The breathalyzer will indicate when to start and stop blowing, and if the sample was not adequate for an accurate reading.

The sensors measure the alcohol level of air in the deep lungs. This value is converted into the corresponding Blood Alcohol Content (%BAC) estimate. Testing is most accurate if subjects have not consumed food or alcohol 15 minutes prior to testing to ensure that there is no residual mouth alcohol.

Why must I wait 15 to 20 minutes after consuming food or alcohol to ensure testing results are accurate?

A breathalyzer is able to calculate this percentage using only a breath sample because of the precise relationship between alcohol in the blood and alcohol metabolized into the lungs from the bloodstream. As such, it is important to make sure the mouth is clear of contaminant (including alcohol) so that the breath sample contains pure lung air, or as close as possible.

What type of maintenance is required to maintain a personal or professional breathalyzer? Do they require calibration?

Over time, all alcohol testers need to be re-calibrated to maintain accuracy. Calibration is a process of checking and adjusting the accuracy of a unit by comparing its results with a known value. For example, a known 0.080 %BAC gas concentration is blown into a breathalyzer, and the unit is adjusted to make sure it correctly reads 0.080 %BAC.

This process is sort of like winding a clock. When the clock is first set it displays accurate time. However, over time the clock gradually drifts a few minutes, and eventually can be off by quite a bit if you do not occasionally reset the clock. When selecting an alcohol tester, it is imperative to select a unit that is capable of being calibrated.

How often should I calibrate my breathalyzer to ensure accuracy?

We recommend re-calibrating breathalyzers with semi-conductor sensors every 300 tests or once a year, whichever one comes first. Breathalyzers with fuel cell sensors will remain accurate for thousands of tests, but should still be re-calibrated annually. Additionally for these models, using the breathalyzer regularly can actually help keep it accurate, as the moisture in exhaled human breath is beneficial to the sensor.

How do I get my breathalyzer calibrated?

See our Calibration FAQs for more information and to complete a form to send your breathalyzer to us for calibration. Our trained technicians will perform a full diagnostic check on all aspects of your breathalyzer as part of the calibration process.

Breathalyzer Accessories

How can I order additional mouthpieces for my breathalyzer? Do I need to replace the mouthpiece after every test?

Please visit our Breathalyzer Mouthpieces page to order mouthpieces and other supplies.

Replacing the mouthpiece after each test is optional if you are testing yourself. For professional testing and screening, it is recommended to change the mouthpiece after each test for safety and performance reasons.

How do I insert a mouthpiece into the breathalyzer?

The mouthpiece should insert easily into the mouthpiece, using the end with the larger inner diameter. It should be inserted approximately 1/8th inch.

How do I clean the mouthpieces if I plan to re-use them?

Clean them with warm soapy water and rinse, or wash them in a dishwasher.

Do you offer Disposable Breath Alcohol Testers?

Yes, we offer the BACtrack SingleShot. It’s a disposable, single-use breath alcohol tester available in three %BAC thresholds: 0.02, 0.05 and 0.08. The BACtrack SingleShot is based on indicator chemistry that changes color in the presence of breath that contains alcohol.

A user will activate the small tube tester, blow through the SingleShot, and the crystals will indicate a positive or negative result based on the Blood Alcohol Content (BAC). For example, the SingleShot .02% will indicate “positive” by changing color when the user’s alcohol level is at or above 0.02 %BAC. These units are accurate, inexpensive, and extremely small, which makes them easy to carry in a pocket.

How to choose a good breathalyzer?

How to choose a good breathalyzer?

Do you want to buy a good breathalyzer? Think about why you

Choosing a breathalyzer for the driver

“Drunk or not?” before this question
Only a doctor could answer for sure. Today, a device for determining
almost every motorist has alcohol intoxication. AND
not surprising! The breathalyzer greatly simplifies life. With him you feel
yourself calmer and more confident, no need to guess, hope for a chance and with
with bated breath look at the road. Alcohol test can be done
even before each trip — it’s simple, fast and very convenient. Is it true,
for everything to really be so good, you still need to know how
choose the right breathalyzer.

Traffic police officers use only good breathalyzers. How to choose the same?

Do you want to buy a good breathalyzer? Think about why you need it

Of course, you don’t have to think about it at all
which breathalyzer is better to choose, and buy something that tells
store consultant. However, in this case, you risk overpaying
or even run into a useless “toy”. If you would like to receive
a good and reliable device for measuring alcohol intoxication,
that exactly meets your needs, it is better to spend time on
choice. And first you need to decide why you need it at all and how
will often be used.

1. For corporate use. High
reliability and 100% reliability of each test can only be ensured by
professional breathalyzers for enterprises with accurate and “hardy”
sensor. There are a lot of such devices on the market and they all cost
not cheap, but in terms of accuracy and reliability they have no equal. They can
conduct up to several tens or even hundreds of tests per day, therefore
perfect for checking the “sobriety” of the organization’s personnel,
for pre-trip inspections, etc. Almost all professional devices
are entered in the State Register of Measuring Instruments of the Russian Federation, that is, their readings have
legal force. In addition, among them there are enough models with
built-in printer and those that support the connection of an external
printer or can be connected to a PC for printing protocols

2. For driver self-monitoring specialists
of our website recommend semi-professional and
quality personal testers. In terms of accuracy and reliability, they
of course, they are inferior to professional breathalyzers for enterprises, but with
correct use and careful attitude show excellent
results. Moreover, some of them are close to professional ones:
have various systems for improving accuracy, can be connected to a PC and

3. For other uses :
checking children and relatives, entertainment, etc. If you don’t drive
car, then high accuracy is not so important. So you can buy
an inexpensive personal gadget that gives indicative readings,
for example, reports only the level of alcohol intoxication or shows
average values. Drivers are not very good at using such a tester.
convenient, but it is a good option for parents who want to know
whether their child drinks alcohol (especially if he began to come late, and
academic performance has decreased), for parties – to spend fun
“alcoholic” contests, etc.

Professional breathalyzer “Alcotest 6810” – expensive, but very accurate

Choosing a breathalyzer for the driver

buy a good breathalyzer for yourself. Then you should first
turn to pay attention to the following parameters:

1. Sensitivity.
The most sensitive are, of course, professional breathalyzers:
“AKPE-01M-01” , “Drivesafe 2” , Alcotest Mark V (Mark 5), “Alcotest 6810” with printer (Drager) , “AKPE-01. 01-01″
expensive, but the high price is justified, because it is precisely such devices that are used
in the official medical examination. Moreover, many of them
equipped with a printer and can print test reports, then
is, you will always have real proof in your hands that you
sober. Among personal sensors, there are also devices of increased
sensitivity (e.g. “AlcoHunter Professional+”, “Dingo E-010” ),
but their testimony is no longer valid.

2. Reliability and quality
largely depends on the country of production and the manufacturer.
Unnamed “Chinese” rarely boast of high quality.
Much “hardier” certified European, some
American and Russian sensors. Among the most common and
requested: French “Ethyway” , American Alcotetor Mark V and
Russian breathalyzer “AlcoHunter Professional +” (by the way, the most inexpensive of the entire “trinity”).

“AlcoHunter Professional+” is as accurate as professional breathalyzers, but costs much less

3. Price. No wonder
that the cheapest gadgets are Chinese. However, they are too unstable
for regular testing, they often “lie” and break, therefore
motorists should remember the saying “the miser pays twice” and
pay attention to others, for example, our domestic ones. Yes, the model
“Inspector” can well afford an ordinary worker, pensioner or

So if you are looking for an accurate and
sensitive alcohol measuring device for daily use,
Take a closer look at “AlcoHunter Professional +” – according to
accuracy, informativeness and reliability, it approaches
professional samples, but it is much cheaper. If you are ready
pay for quality and high sensitivity, then you may
German “Alcotest 6810” with printer (Drager) or domestic
“AKPE-01.01-01”. Well, “Inspector” will be a real boon for those
who is looking for a very inexpensive option without sacrificing quality!

Which breathalyzer to choose?

Breathalyzer is a device for measuring the level of alcohol in a person’s breath. Despite the fact that breathalyzers have appeared relatively recently, they have already gained a reputation as reliable and necessary devices not only for police officers and professional drivers, but also for motorists for whom safe driving is always a priority. If you decide to buy a breathalyzer, first of all you should know what breathalyzers are and what is their main difference.

All breathalyzers are divided into three types:

  • professional breathalyzers – most often used by traffic police officers;

  • medical – for medical examination;
  • personal breathalyzers – for personal use and self-control.

    In order not to make a mistake with the choice and buy a good breathalyzer, it is important to know that they are all equipped with a semiconductor or electrochemical sensor. A semiconductor sensor, unlike an electrochemical sensor, requires more frequent maintenance. Breathalyzers with a semiconductor sensor cannot be used more than 2 times a day, but they have a low price compared to devices with an electrochemical sensor. Breathalyzers with an electrochemical sensor are modern, reliable and most accurate devices designed for frequent use. Having decided to buy a good breathalyzer, you should not save on the purchase, because you are buying a breathalyzer for a long time.

    We recommend that you opt for breathalyzers with an electrochemical sensor. To date, several companies can be distinguished among the manufacturers of breathalyzers: Alcogran, ACS, Drager, Dingo. By purchasing products from these manufacturers, you become the owner of reliable and accurate devices for measuring the level of alcohol in exhaled air. If road safety is not just words for you, but a call to action, if you always want to keep the situation under control, we recommend that you purchase a breathalyzer. But before you buy a good breathalyzer, look at the reviews of other users that can be useful for you. Everyone who has already bought a breathalyzer, most often speak positively about these devices. After all, they are designed to provide additional safety on the road, they help many not only to save a driver’s license, money and time, but also the most precious thing – human life. Now you know which breathalyzer is better to choose and what to pay attention to first of all. We recommend visiting the “Alcotesters” section on our website.
