Proprietary Sensor Technology. Unparalleled Precision.

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

Xtend® Fuel Cell Sensor Technology

Engineered by BACtrack from technology used in experimental vehicle fuel mixing, our proprietary Xtend® Fuel Cell Sensors deliver the most accurate, consistent BAC results.

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.
