Alcohol Breathalyzer Tester Digital Breathalyser – Breath

Tips:

Before use, please follow the operating steps in the manual and install the mouthpiece.

Avoid testing immediately after drinking. For accurate measurement results, it is recommended to wait 20 minutes after drinking before performing the test, and rinse your mouth with water before use.

The product has a 15-second countdown when turned on. During this time, please do not blow air as this is the instrument’s self-clean preparation time.

After the 15-second preparation, a 10-second countdown is displayed. At this point, blow evenly and continuously for 4-5 seconds, without blowing too hard or too weak, and repeat this process 3 times, then take the average of the results.
