MicroCheck® Sensor Technology

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.

Optimal Breath Capture

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. To enhance accuracy, all BACtrack pro-grade models feature a miniature solenoid air pump to test only air from the deep lungs.


Proprietary Sensors

Our Advanced MicroCheck® alcohol sensor delivers reliable and accurate BAC results, every time you test


Mouthpieces

Includes washable, disposable mouthpieces to improve accuracy by collecting the highest quality sample, and to allow you to test others safely.

The folding mouthpiece pulls out during testing and slides back down during storage – blow for accurate BAC results in just 5-seconds.
