The Bactrack keychain breathalyzer relies on advanced microcheck sensor technology, where it’s Semiconductor Oxide sensors use a tin-oxide substance so as to come up with accurate bac results. This is a bit different from the Fuel Cell Technology that’s used by the Alcohawk Pro, but you can still rely on them both for on point readings. The bactrack keychain breathalyzer is also pretty easy to use, as it only has one button, and a red lit LCD display for easy visibility. It’s fold-out mouthpiece ensures that no ambient air gets captured, so as to keep the results clean and accurate.

At a weight of about 57 grams, the bactrack keychain breathalyzer is really ultra portable, so you shouldn’t have an excuse of not being able to carry it around. It’s got a keychain that you’ll easily be able to attach your keys to, and in doing so, you’ll have a reason to carry it wherever you go. It’s a lot smaller than the alcomate premium al7000, and will probably be a lot easier to move around.


To keep it as small as it is, the Keychain breathalyzer bactrack was designed to only accommodate 1 AAA battery, so if you use it pretty often, you can expect to be changing the battery quite often. There’s an aaa battery that’s included when you first purchase the breathalyzer, so you’ll be able to start using it immediately after you buy it.
