Digital Breath Alcohol Analyzer with LCD Display for Accurate Testing

New, portable, and stylish design Advanced flat-surface alcohol sensor Rapid detection, quick response, and fast recovery High quality, high accuracy, and high sensitivity SMD assembly for stable performance Smart MCU control Direct testing process with LCD indication Digital LCD display with light blue backlight Audio warning when readings exceed preset limits Automatic sensor fault self-check Battery-saving design with low-voltage indication Alcohol Test Tips: - Wait at least 20 minutes after consuming alcohol before testing. - If another person tests immediately after you, they should wait 5 minutes. - If the reading exceeds 0.05% BAC, the alarm will sound — do not drive. - If the reading is below 0.05% BAC, it indicates a safe level for driving. How to Use: 1. Open the battery cover and insert 3 AAA batteries according to polarity. 2. Press the “Start” button. A short beep will sound, the backlight will activate, and the screen will display a countdown from 100 to 000. The lower part of the screen shows “WAIT”, indicating the preheating phase. Do not blow during preheating — this may affect accuracy. When preheating completes, “WAIT” disappears, the device beeps, and “BLOW” appears along with a moving “C” symbol — you may begin blowing. 3. Take a deep breath and blow steadily and continuously into the mouthpiece until the device beeps. Stop blowing immediately after the beep. 4. After blowing, the screen displays “TEST” while analyzing the sample. Do not blow again during analysis — this may affect results. Once complete, the measured alcohol concentration appears on-screen and remains visible for several seconds before the device powers off automatically.
