Alcohol Detector, also called breathalyzer, is used to calculate the levels of alcohol in the blood. It uses alcohol sensing technology to give accurate Blood Alcohol Content (BAC) instantly. Alcohol test machine can be used both for professional and personal purposes. As muscle mass, weight, and recently consumed beverages or food affect the blood alcohol content, it becomes almost impossible to measure intoxication level without a tool like alcohol detector.

How to use Alcohol Detector?

Take a alcohol level detector and attach a mouthpiece to it.
Switch on the power button.
Wait till “blow” is displayed on the screen. This warms up the unit to the optimal test conditions.
For around 4 seconds, keep on blowing in the mouthpiece. Most models will produce a beep sound when you will start blowing. Do not stop blowing until the beep sound stops.
Try not to blow any saliva, smoke or other contaminants into the mouthpiece because this can damage the sensor.
Wait for a few seconds to allow the alcohol detector to analyze your breath.
Result will be shown to you in around 15 seconds. This time varies from model to model and manufacturer to manufacturer.
Turn off the breathalyzer when you are done with the test. Some may automatically shut off if not used for two minutes.
