This fuel cell breathalyzer uses superbly accurate technology to carefully read your breath alcohol level. It’s about the same size as a smartphone and can be stored discretely in your pocket. It’s operated via one button and gives fast, accurate results on a four-digit display. It comes with mouthpieces and a carry case.
The alcohol breath tester never needs to be sent away for calibration, you simply swap the sensor cartridge which takes less than a minute.
