The Andowl Qcs12 keychain-style breathalyzer measures the alcohol content in your breath and uses a semiconductor sensor. The reading is displayed on the LCD screen, while an audible alert indicates the result. The device is activated with a single button, preheats for approximately 20 seconds, and then requires you to blow into it for a few seconds.
