What is a Breathylyzer

A breathalyzer is a device which measures the level of alcohol in the body. They are different in mode of operation: some use 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 the driving under the influence (or DUI) is a very unpleasant crime and you are sure to avoid it.

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 breathalizer you do not need to know too much. 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 device.

The first one is Range and Accuracy. No need to say you must be sure the alcohol level does not exceed an allowed limit (it depends on a 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. Also, no breathalyzer can be faultless, so you need to check the accuracy too.

The next important feature is 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. 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.

The last feature to consider is the Usability - 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 you can drive (if your alcohol level is too high), advise you how much you should drink, and so on. Other devices go with a set of interchangeable mouthpieces.
