The Alco-Sensor FST breathalyzer from Intoximeters is an approved Evidental Breath Testing device. With evidential accuracy exceeding +/- .005 at .100 BrAC, the Alco-Sensor FST is the most widely used breathalyzer in law enforcement, corrections and substance abuse treatment programs worldwide.

If you require accurate results that will stand up in a court of law, choose item 207-LE and pair it with an evidential gas quality tank for monthly accuracy checks. If you need accurate results but do not need results to hold in a court of law, 207-CAN gives you the device and a non-evidental gas can for accuracy checks.
