This isn’t the first or only personal breathalyser available, but it uses an internal fuel cell to measure alcohol in your breath. This method is one of the more accurate ways to test and is closer to the technology police use to patrol the streets too. Testing is simple and blood alcohol is presented as a percentage on the digital display. Includes 3 x mouthpieces and a storage case. Of course all measurements are an indication only and you should only use them as a guide. The safest blood alcohol to drive with is zero. Additional mouth pieces: QM7309
