The digital alcohol tester uses an electrochemical sensor to measure blood alcohol content. The breath sample takes 6 seconds at an airflow rate of 10 L/min, while the airflow stop sensor monitors sampling.

The four-digit LCD has a blue backlight and displays “HI” when the measurement range is exceeded. Exceeding the alarm threshold is indicated by an audible alert and a change in the display color.
