How do I use my portable breathalyzer?

A breathalyzer is a device used to estimate a person’s blood alcohol content using a breath sample. The device estimates the individual’s blood alcohol content (“BAC”) as grams of alcohol per mL of blood. Portable breathalyzers are suitable for use in the workplace, law enforcement or for home use.

How do I use my portable breathalyzer

Breathalyzers are breath analysis testing instruments into which a suspect must blow a stream of air. For most models, a user simply blows through the mouthpiece for 5 seconds. The blowing is similar to blowing out a candle and the user should blow evenly for the entire 5 seconds. The portable breathalyzer will indicate when to start and stop blowing.

To ensure accurate test results, you must wait at least 20 minutes from the time of your last drink. Doing so ensures you are testing for the alcohol deep within your lungs and not from any alcohol residue left in your mouth. This greatly reduces any chance of false positives and sensor saturation.

Breathalyzers estimate BrAC based on a breath sample, and will not be as accurate as when a sample of blood is tested for alcohol content. However, fuel cell breathalyzers are highly accurate if calibrated according to the manufacturer’s recommendations. When used correctly, breathalyzers provide a very close estimate of our BrAC.
