Best Breathalyzers

Most personal breathalyzers have often not been known to last for very long, or for going long periods of time before needing to be recalibrated. This device, however, boasts long-term reliability against other similar testers. The time spans between recalibrations are pretty large - up to 200 tests, so you can get quite a bit of use out of the device before needing to worry about its accuracy. The device shows the accurate alcohol level within several seconds of blowing through the mouthpiece, so you also don't have to wait very long to get the test results. The battery can last up to 1500 tests, though if you use the device quite often you will need to change the battery more often. Still, this holds up quite well against most other similar devices on the market, so those who opt for this device will find these features to add quite a bit to its convenience of use.

Speaking of the device's convenience, it includes a backlit LCD screen that will display your test results in large, clearly legible characters within seconds of taking the test, making it easy to see the results in any conditions. Also included are 6 plastic mouthpieces and a small pump which grabs more breath air to ensure a more accurate result. This lets you share use of the device among several people if more than one needs to check their blood-alcohol level. Keep in mind that if you plan to use it for testing alcohol levels of people other than yourself, you might need to buy a few sets of mouthpieces in advance, but this of course remains true of any breathalyzer on the market. Regardless, most people who opt for this device should find it to be perfect for their needs.

There are often questions about any given breathalyzer's accuracy, but with this device you simply don't need to worry about it at all. This breathalyzer uses the highly accurate fuel cell sensor technology Suracell, which makes the reliability of the unit unmatched, along with extremely accurate test results. The unit is powered by two 1.5 V AAA batteries, which give you a sufficiently long battery life of up to 500 tests while also providing easy replacement options. To help extend the battery life, the unit features an auto-shutoff feature just in case you forget to turn it off after using it. Although the battery life isn't the greatest of all of the devices we've looked at, most people who only need to use it occasionally should find it to be more than sufficient.

This breathalyzer is relatively easy to control, thanks to the simple display. The controls of this device are quite easy to use, making it one of the more intuitive breathalyzers on the market. The memory of the device allows you to see the last 10 measurements along with the time elapsed since the last measurement, as well as recall how many tests you have left before needing calibration, so there won't be any guesswork when it comes to reviewing current or past test results. The device itself is made in a laconic design, and comes with a hard zippered case, so that if necessary it can be a good gift to anyone. All in all, this highly functional breathalyzer will serve anyone well who needs to test their blood alcohol level regularly.

This device uses the BluFire Fuel Cell Sensor, a patented sensor technology by BACtrack that gives you professional quality results, making it useful for both regular users and professionals alike. The extremely compact design of the device has no negative effect on battery life, as the single AAA battery necessary to power the device should last for up to 300 tests. This makes it one of the most energy-efficient breathalyzers on the market, even if not the longest lasting, so it's a great option for those who only need to use it every once in a while instead of quite often. The only negative here is that the device does not include a battery, but that shouldn't be a problem for most people, as such batteries can be purchased anywhere.

This is one of the most portable breathalyzers on the market, as it easily fits on a keychain and is hardly noticeable while in your pocket. The white casing of the device also makes it seem inconspicuous, as it looks like little more than a keychain watch at first glance. This belies the high accuracy and usability that the device provides to any user. Not only is it compact, but it also includes Bluetooth functionality that lets you sync it with your smartphone while in "App Mode", giving you the ability to compare test results and track your drinking habits over a period of time. This provides a level of functionality and usefulness that is well beyond what most other breathalyzers are capable of. For anyone who wants high portability and accuracy along with a highly flexible range of use, this breathalyzer is certainly the best option.

Breathalyzers don't do much good for anyone if they don't give accurate readings. Thankfully, this model is quite accurate, and in fact is one of the most accurate ones we've seen. All blood-alcohol readings fall within an accuracy range of +/- 0.010% BAC, so you can be assured that whatever reading you see is correct. On the downside, this model doesn't quite have the testing range of some others, but it still has a large enough range to test all but the highest possible readings. Simply put, if this device can't detect your blood-alcohol range, then it is definitely too high to drive.

As stated before, the device is quite simple to operate, and it has a few conveniences that help make it even easier. For instance, the backlight of the LCD display will light with different colors depending on the blood-alcohol level, making it easy to see whether or not you have had too much to drink at a simple glance. This model also contains memory for the previous 32 test results, letting you do a comparison of your testing history. The device is powered by 3 AAA batteries, with each set of fresh batteries giving it enough power for up to 1000 tests. This kit even comes with 5 separate mouthpieces, so you can always have an extra one on-hand. Simply put, this breathalyzer is one of the easiest to use and most accurate models on the market.

The difference between this model and many others, though, is in the extra features it provides for not just testing your blood-alcohol level, but in alcohol's total effect on your body. It all starts with the device's readings, which are quite accurate thanks to the Advanced BluFire® Fuel Cell Sensor, even when compared to many of the most accurate models available. This breathalyzer not only tells you your blood-alcohol level, but it even tells you how much time you have to wait until you are completely sober. This lets you enjoy yourself and have a good time with friends while knowing how long it'll take to sober up, or help you with making a quick decision about whether or not you should call an Uber or taxi to go home.

Along with the above feature, this breathalyzer can also connect to your smartphone through built-in Bluetooth connectivity, and it even works with the HealthKit app, which includes additional features for tracking the alcohol's effect on your body, and even providing a way to call an Uber directly from the app. The device is powered by a single AAA battery, which will last for up to 300 tests, so you won't need to change batteries very often. All in all, this breathalyzer offers a lot more than just tracking your blood-alcohol level, making it a great purchase for anyone who wants to be aware of their health at all times.
