Smart alarm function: Depending on the different road regulations in European countries, the alarm value can be set by you (0.20‰ BAC / 0.30‰ BAC / 0.50‰ BAC / 0.80‰ BAC). If your blood alcohol level exceeds the set value, the buzzer will sound.

One-click testing: The semiconductor breathalyzer is easy to use. Simply insert the batteries.

Requires 2 AA batteries (not included) and press the power button to start the test. Reminder: If you have already consumed alcohol, it is recommended to wait 20 minutes before taking the test.
