The Mission Breath Alcohol Detector is intended to measure alcohol in human breath. Results are used in the diagnosis of alcohol intoxication. The Mission Breath Alcohol Detector is a semi-qualitative rapid screening test. It indicates relative Blood Alcohol Concentration (BAC) at 0.02% cutoff level. Each detector contains crystals that detect a specific cutoff level of BAC. Alcohol reacts with the crystals in the detector to produce a color change. If the test is positive, the amount of alcohol in the breath is greater than or equal to the cutoff level of the detector. 3-year shelf-life at room temperature Results in 2 minutes Easy to perform and interpret
