How does a LifeSafer breathalyzer work? The user blows into a mouthpiece, which channels the breath into a sensor chamber. Inside, the alcohol content is measured based on its chemical reaction with the sensor. The device then processes this data and displays the blood alcohol concentration (BAC) on a digital screen.
