An alcohol detector, or breathalyzer, is a portable device used to estimate blood alcohol concentration (BAC) by measuring the amount of alcohol in your exhaled breath. 1. Blowing air: You blow into the device mouthpiece. 2. Sensor analysis: The internal semiconductor or fuel cell sensor detects alcohol particles. 3. BAC calculation: The device calculates your breath-to-blood ratio and displays the estimated BAC level on an LCD screen. Personal testers: Compact, battery-operated units for individual use. Professional and police-grade units: High-accuracy devices with advanced fuel cell sensors used for legal or workplace testing.
