Every BACtrack breathalyzer is engineered around the two factors that most influence accuracy: sensor type and optimal breath capture.
Our consumer breathalyzers employ Advanced MicroCheck® Sensor Technology. Using a semiconductor sensor as a base, these sensors go through a patented burn-in process, which delivers more accurate and reliable results when compared to standard semiconductor sensors.
Breathalyzer accuracy begins with an effective breath capture mechanism. BACtrack breathalyzers are carefully designed to exclude ambient air, fumes, and other airborne gases that could contaminate results.
Thoughtful design, unrivaled accuracy.
Our Advanced MicroCheck® alcohol sensor delivers reliable and accurate BAC results, every time you test.
Includes washable, disposable mouthpieces to improve accuracy by collecting the highest quality sample, and to allow you to test others safely.
Mini solenoid breath pump ensures the most accurate and efficient breath capture for testing.
