Accuracy You Can Depend On: BACtrack's Sensor Technology
Accuracy You Can Depend On
BACtrack has established itself as the most trusted and bestselling breathalyzer brand, with over 14 years of expertise dedicated exclusively to breath alcohol testing. The company made history as the first company ever to receive U.S. FDA 510(k) marketing clearance to legally sell breathalyzers to consumers for personal use.
Performance testing results
BACtrack conducted rigorous comparative testing of its Mobile Pro model against both police-grade equipment and lower-quality alternatives. The study involved 8 subjects tested over two separate six-hour periods, yielding 162 total tests. Results showed that the BACtrack Mobile Pro closely mirrored the DataMaster, particularly at BAC levels below 0.08%, while competitor novelty devices performed inconsistently throughout testing.
Testing parameters:
- Dates: August 29, 2013 and November 13, 2013
- Duration: 1100–1730 hours
- Unit serials: DKH-0922, DHA-0524
Independent validation
Multiple news organizations have conducted their own accuracy assessments. NBC affiliates, CBS affiliates, and Car & Driver all reported that BACtrack demonstrated superior accuracy compared to other commercially available breathalyzers when tested against police-standard equipment.
Core technology
BACtrack employs two proprietary sensor systems:
Xtend® Fuel Cell Sensors are engineered from experimental vehicle fuel-mixing technology, delivering the most accurate, consistent BAC results.
MicroCheck® Sensors use semiconductor technology enhanced through a patented burn-in process, providing improved accuracy and reliability versus standard semiconductor options.
Both systems incorporate optimal breath capture mechanisms designed to exclude ambient air contamination.
Quality assurance
BACtrack maintains ongoing quality control through human subject testing. This approach simulates real-world usage patterns, natural breath variations, and individual lung capacity differences. Subjects consume alcohol, wait 15 minutes, then test sequentially with DataMaster police equipment and BACtrack devices for comparative analysis.
The reference standard used in testing is the DataMaster, a $7,000 desktop unit admissible in court proceedings, regularly deployed by law enforcement agencies.
