{wiki=Breathalyzer}
A Breathalyzer is a device used to measure the blood alcohol concentration (BAC) in a person's breath. It works by analyzing the breath of an individual after they have consumed alcohol. When a person exhales into the device, it estimates the amount of alcohol in their bloodstream based on the concentration of alcohol vapor in the breath. Breathalyzers are commonly used by law enforcement officers to test drivers for intoxication during traffic stops or sobriety checkpoints.
