2024 Automatic Alcohol Tester Professional Breath Alcohol Tester Rechargeable Breathalyzer Alcohol Test Tools

Everything arrived, it works. The accuracy is not known. Of the cons : Not complete set. There should be a lace, which is prescribed even in the instructions, but there is none. Instructions are in Chinese only. I had to translate. Not a word about the operating modes, of which there are 5, plus two additional ones. It shows mg/100ml on the 0th mode (the first one as soon as it was turned on), to convert it to ppm, you need to divide it by 100. On other modes, it is not at all known what it shows.

It's cool, it even seems to correspond to the per mille, it shows how much it lies, I don't know, but we won't get behind the wheel anymore

Only in Chinese, but with a translator it's fine, it works
