An ideal choice for professionals and anyone who requires the most dependable BAC results, BACtrack Pro Series breathalyzers deliver police-grade accuracy and consistency every time you test.

Pro-Grade Breathalyzers

Equipped with police-grade Xtend® Fuel Cell Sensor Technology, these models are ideal for situations where the highest level of accuracy and consistency are required.

Accuracy You Can Trust

All BACtrack Professional Series breathalyzers employ our Xtend® Fuel Cell Sensor Technology and an Internal Air Pump.

Xtend® Fuel Cell Sensor Technology

Unlike any alcohol sensing technology in the world, the sensors used in our BACtrack Pro Series Breathalyzers were originally created for use in experimental military assault vehicles. Adapted by BACtrack for breath alcohol measurement, this proprietary Xtend® Fuel Cell Sensor technology is what sets BACtrack Breathalyzers apart from the rest, allowing us to deliver the most accurate BAC results on the market.

Miniature Solenoid Air Pump

All Pro Series Breathalyzers also use a miniature solenoid air pump to more precisely collect a user's breath sample. During use, you can actually feel the "click" of the pump collecting the breath sample.

Department of Transportation

The BACtrack S80, Element, and Trace breathalyzers have been tested by, and meet the requirements of, the DOT/NHTSA for a personal breath alcohol screening device. Additionally, BACtrack became the first company ever to receive U.S. FDA 510(k) clearance to market breathalyzers to consumers.

Why Choose Xtend® Fuel Cell Sensor Technology


  • Precise Results

    The linear response of the Pro Series’ Xtend® Fuel Cell Sensor Technology provides precise results over the complete range of alcohol concentrations expected in the breath, from 0.000 to 0.400 %BAC, including trace amounts of alcohol.


  • Consistency

    Pro Series models produce the most consistent and reliable results. For example, they are more likely to show the same test result when someone is tested repeatedly in a very short period of time.


  • Sensitive Enough for High BAC Testing

    Pro Series models are more accurate at higher BAC concentrations. For example, if someone is very intoxicated, for instance 0.22 %BAC, these models are more likely to provide an accurate test result as compared to semiconductor models, which are less accurate higher BAC values.


  • No False Positives

    Pro Series models will not show a false positive for someone who is diabetic or on a low calorie diet due to the presence of acetone, unlike some semiconductor models that may.


  • Long term Reliability

    Extended sensor life, maintains accuracy for up to thousands of tests, delivering long-term reliability.


  • Faster Warm up Time

    Pro Series Models offer a faster warm up time, a benefit when conducting high volume and back-to-back testing.


  • Longer Battery Life

    Low power requirements enable up to 1,500 tests on one set of AA batteries!
