Ultra-Portable Design

The compact BACtrack S35 fits perfectly in the palm of your hand and is easily stored in a purse or pocket.

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.


BACtrack 35 Personal Breathalyzer

The BACtrack S35 is one of the smallest, sleekest breathalyzers on the market. Designed in California with ease of use and style in mind, the S35 harnesses a powerful proprietary sensing technology and a specially tuned algorithm, delivering BAC results with unheard of accuracy at this price point. Just pull it out, turn it on, and blow into it for five seconds. Your estimated BAC will display on the cool, Caribbean blue LCD screen.
