portable alcohol tester

A portable alcohol tester is a handheld device used to measure a person's blood alcohol concentration (BAC) quickly and accurately. It works by analyzing a breath sample, typically through a mouthpiece, to determine the level of alcohol present. These devices are commonly used by law enforcement for roadside sobriety checks, but are also available for personal use. They provide instant results, helping to ensure safety by confirming whether someone is over the legal alcohol limit for activities like driving. Modern portable testers are compact, easy to operate, and often calibrated regularly for accuracy.
