Digital Display Alcohol Breath Tester

This device provides accurate BAC with readings clearly on a LCD display. It features 10s countdown to get ready to test and 5s response time. In use, different symbols get presented on display for instruction like warm-up symbol, blow symbol, low battery symbol, power-off symbol which makes every step easy. And it alerts you when your BAC level is 0.02% BAC(or 0.2g/l) to 0.05% BAC(or 0.5g/l) by showing a Caution symbol on display, it beeps and shows a Danger symbol on display when your BAC level is equal & over 0.05% BAC(or 0.5g/l). The device will turn off about 35 seconds after the result is displayed to save energy which means even 2 AAA batteries can run for a very long time.
