Which instrument is used to measure BAC from breath?

• A. Breath Test Meter
• B. Breath Gauge
• C. Breathalyzer
• D. Breath Analyzer

Answer: (C)

Measuring BAC from a breath sample relies on the link between alcohol in the blood and in the deep-lung air that you exhale. The instrument for this purpose is designed to sample that breath and translate the ethanol content into an estimate of blood alcohol content. The widely recognized term for this device, especially in law enforcement and exams, is breathalyzer. Other labels like breath gauge or breath test meter aren’t the standard names used for this tool, and while breath analyzer is a real descriptor, the conventional term students are typically taught is breathalyzer. So the best answer is breathalyzer.
