Proprietary Sensor Technology.
Unparalleled Precision.

Every BACtrack breathalyser is engineered around the two factors
that most influence accuracy: sensor type and breath capture.

Advanced MicroCheck® Sensor Technology

Our personal breathalysers employ Advanced MicroCheck® Sensor Technology. These sensors go through a patented burn-in process, which delivers more accurate and reliable results when compared to standard semiconductor sensors.

Effective Breath Capture

Breathalyser test accuracy begins with an effective breath capture mechanism. BACtrack alcohol breathalysers are carefully designed to exclude ambient air, fumes and other airborne gases that contaminate results.
