The C-07 digital alcohol tester detects and measures alcohol concentration in breath for personal checks. The portable device has a built-in rechargeable battery and includes a USB/micro USB charging cable. After switching it on, it warms up for 15 seconds, then starts a 10-second countdown before you blow into it.

Results are displayed on the LCD screen, while light and sound alerts vary according to the reading: a green light for concentrations below 0.2 g/L; a yellow light and audible signal from 0.2 to 0.8 g/L; and a red light with a rapid audible signal at 0.8 g/L and above. This device is not a certified instrument for legal or medical testing, and its reading does not replace an official measurement.
