Always wanted to check if you are able to drive after drinking a few shots at a party?
The alcohol breathalyzer is your solution for testing your breath after a night of drinking.
It works by exhaling into the device, which measures the amount of ethanol present in the breath. An electric current is produced and measured by a microprocessor, then displays the results.
