How Alcohol Meter Works?

A fuel cell measures alcohol content by creating a chemical reaction that oxidizes the alcohol in the breath sample and produces an electrical current. The more alcohol that is oxidized, the greater the current. The current is measured to determine the subject's BAC.

How does the alcohol test work?

Alcohol breath-testing devices use the amount of alcohol in exhaled breath to calculate the amount of alcohol in a person's blood, also known as blood alcohol concentration (BAC). Here's how: When a person drinks alcohol, it goes into the stomach and small intestine and is quickly absorbed in the blood.

How do breathalyzers detect alcohol?

Alcohol's concentration into the air present in the alveoli encourages concentration of the alcohol in the blood. When this alcohol concentrated air is exhaled, the breathalyser can easily detect it.
