Pinpoint Accuracy

With many different devices nowadays, it's quite fashionable to have them connect to the ever present smartphone. This same trend is actually happening with breathalyzers as well. The only problem with this is, needing to connect to an extra device can make the operation of the device more complicated, thus removing any convenience it may add to your life. The BACtrack S80 breathalizer, however, does not require connection to any devices and works independently. You can use it by yourself or for professional use but make sure to have mouthpieces. This model is one of the most accurate breath tester devices recommended by the police and medical associations. It measures alcohol in your breath from 0.000 to 0.400% BAC, while the accuracy is +/- 0.010% BAC, giving you fully accurate readings that won't deviate much at all from test to test. By using this device, you can get an accurate reading and be sure of the results.

Long Battery Life

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.

Suitable For Everyone

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.

Test Your Breath

Breathalyzers can be quite handy to have when you have been having a few drinks with friends, but when you find yourself having had too much to drink, the simple functionality of a breathalyzer can be a bit limited, especially if you are waiting to sober up enough to drive. The iSOBER 30 Breathalyzer is a sufficiently functional device which not only gives clear results with a small margin of error of +/-0.005%BAC, but also allows you to see the time elapsed since the last measurement, and also recalls how many tests you have left before calibration is necessary. Warm up time of the breathalyzer is a bit low, as it can take up to 4 minutes before it is ready to use, so make sure that you start up the device with enough time to warm up before you need to use it. Despite this small drawback, the overall range and accuracy of this device is nothing at all to complain about, especially if you need to check your breath several times in a row and need to compare the results.

Advanced Sensor

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.

Simple and Beautiful Design

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.

Breathalyzer on a Keychain

Most people aren't used to having a breathalyzer with them, and if you have one, there is always the possibility of forgetting to bring it with you whenever you head out for some drinks. This, of course, defeats the purpose of having one in the first place, so it's always extra handy to have one that you will always carry with you without needing to remember it. The BACtrack BT-C6 Keychain Breathalyzer is the perfect option for people who need to ensure that they have a breathalyzer with them wherever they go, thanks to its usable and highly compact design. The device has a range of 0.000 to 0.300% BAC, with an accuracy of +/- 0.010% BAC, giving you a good range of testing with a high degree of accuracy. Not bad for a device that can easily fit on anyone's keychain, which of course helps greatly in ensuring that you always have it with you. After all, it's hard to go anywhere if you leave your keys at home, so keeping your breathalyzer with them ensures you will never forget it.

BluFire Fuel Cell Sensor

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.

Inconspicuous

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.

Always Ready

Having a breathalyzer with you whenever you have had drinks while out on the town can mean the difference between a pleasant night with friends and family or an unpleasant one in jail. And that's not to mention the worst-case scenario, either. Having a breathalyzer that can be ready at a moment's notice, though, is even better, and that's what you get with the Rofeer Breathalyzer. This device takes only 2 seconds to turn on, and requires no more than 15 seconds for warm-up, which means that you can use this on a whim at any point, even when you need to make a quick decision about whether or not to get behind the wheel. You won't have to wait an eternity for the test results to show you your blood-alcohol level.

The overall design of this breathalyzer makes it one of the easier and most convenient models on the market. The device, while being a bit larger than some others, is still plenty small enough to fit in your pocket, and features a sleek black case that makes it look more like a phone than a medical instrument. The test results appear on the backlit LCD display in large numbers, making it easy to read, and operating the device is about as simple as it gets. Just turn it on, blow through the mouthpiece, and your blood-alcohol reading will appear on the screen.

Accurate Readings

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.

Test With Ease

Most breathalyzers have one simple job, which is to test your blood-alcohol level, and rarely do they offer any additional kind of functionality. Sure, you can save your test results in memory, and some even let you sync to your smartphone for easy readability, but few really offer much beyond that. With the BACtrack C8 Breathalyzer, though, you actually get much more than the simple functionality that is offered by most other models.

First, though, the device itself won't be very convenient to use if it isn't portable. Thankfully, this model definitely is. Although it is a bit larger than some other models on the market, it is still plenty small enough to easily fit in a pocket or purse. Although this model doesn't include a keychain connector, it is just as small as some other models that do. In short, it is small enough to take with you anywhere.

Operating the device is quite simple, as it requires just the push of a button to turn on and then blow into the receptacle. Within just a couple of seconds, you'll get your blood alcohol level on the LCD screen, which shows all values in large, easy-to-read characters so you can see the results in any state. The screen is also backlit, so you can easily read it even in a dark club or bar, or anywhere that has little ambient light.

Track Your Health

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.

What Is a Breathylyzer?

Most people enjoy having a good drink from time to time, and that often will happen in various places. Whether you are at a bar with friends, or at a restaurant with family, alcoholic drinks can often make time go more smoothly. However, there is always a danger to drinking too much, especially if you are driving, and it can be a fine line between just having enough to relax and having too much to drive. This is where having your own breathalyzer can help save the day.

A breathalyzer is a device which measures the level of alcohol in the body. They are different in mode of operation: some use a platinum fuel cell sensor, others are based on semiconductors. If you think you do not need a car breathalyzer you are mistaken - you need to know the alcohol level in your body when you drive after drinking some alcohol. Keep in mind that driving under the influence (or DUI) is a very unpleasant crime and you certainly want to avoid it. Of course, there are even worse repercussions for driving after having drunk too much, which are even worse than a DUI. Avoid these consequences and always keep an eye on your blood-alcohol level with a breathalyzer.

If you are a driver, you might also be interested in car backup cameras, whereas those who have just received the license might want to read about parking sensors.

What Features to Compare

When you are about to choose a car breathalyzer, there really aren't a whole lot of factors that you will want to pay attention to in a device. The Internet is full of different breathalyzer reviews but most of them are overloaded with technical details and are difficult to understand. That is why we have done our best to make our breathalyzer review crystal clear and informative. There are several basic features that will help you select the best breathalyzer for your needs, which are all listed below.

Range and Accuracy

The first characteristic to pay attention to is the range and accuracy of the device. It should go without saying that you must be sure the alcohol level of your blood does not exceed an allowed limit (it depends on the state you live in). The range is measured in % BAC and the best breathalyzers ensure the accuracy from 0.000% BAC while less precise devices start from 0.00% BAC. When choosing a device, make sure that you choose one that is precise enough to give you a reading that you can take as fact instead of having to guess if the reading is too high or too low. Also, no breathalyzer can be faultless, so you need to check the accuracy of any breathalyzer you purchase, and account for that discrepancy whenever you use it.

Sensor and Battery

The next important feature is the sensor and battery. Every device requires batteries (different types) and the time it remains active is different. A lot depends on how often you take measurements - if you do it every day, then no matter how good a battery is - you will not be able to use a breathalyzer for a year on a single set of batteries. Most breathalyzers measure the battery time in the number of tests you can take before needing to replace the batteries, so make sure that you pay attention to this number with any unit you purchase. Also, every sensor has to be recalibrated from time to time, otherwise, the device will not be accurate enough. Some models need recalibration every 200 breathalyzer tests, whereas others can go for different lengths of time between recalibration.

Usability

The last feature to consider is the usability of the breathalyzer - a car breathalyzer should be easy in use and simple to configure. The best devices work via a special breathalyzer app for an Android or iOS device (smartphone or tablet, for example). The breathalyzer app will also count the time until you can drive (if your alcohol level is too high), advise you how much you should drink, and so on. Other devices come with a set of interchangeable mouthpieces. For whichever device you choose, make sure it comes with everything that you want or need the device to have.
