Alcohol breath testers, also known as breathalyzers, are devices used to estimate a person's breath alcohol concentration (BAC). These portable devices work by analyzing the alcohol content in an individual's breath sample. Breathalyzers are commonly used for personal and professional purposes, such as monitoring alcohol levels before driving or for workplace safety. They utilize different technologies, such as fuel cell sensors or semiconductor sensors, to provide accurate and reliable readings. Breath testers vary in features, detection ranges, response times, and display options. It's important to note that breath testers provide estimates and should not be relied upon for legal purposes.
