I bought two of these, one for my wife and one for myself, and we have been very pleased with them so far. I compared results across the two devices and got the exact same reading, which is reassuring of their accuracy.

Accuracy You Can Trust

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 professional breathalyzers feature a miniature solenoid air pump to test only air from the deep lungs.

Xtend® Fuel Cell Sensor Technology

Engineered from technology used in experimental vehicle fuel mixing, all BACtrack professional breathalyzers utilize proprietary platinum-based Xtend® Fuel Cell Sensors which deliver the most accurate, consistent BAC results, with police-grade accuracy.

DOT/NHTSA Tested and Compliant

All BACtrack professional breathalyzer meet the federal requirements of the Department of Transportation and National Highway &Traffic Safety Administration for personal breath alcohol screening devices.

The Military & Law Enforcement

Police departments rely on BACtrack Breathalyzers as preliminary screening devices during DUI traffic stops to determine if someone is possibly intoxicated. The Military use BACtrack Breathalyzers to ensure its service men and women are safe and sober while on duty.

Health Professionals

While blood testing is the most accurate way to determine BAC, this process is invasive, time consuming and requires trained professionals. With a BACtrack Breathalyzer, medical staff can quickly and easily estimate the BAC of their patients, in a fraction of the time.

Alcohol Treatment & Recovery Centers

Alcohol Treatment and Recovery Centers use BACtrack Breathalyzers to keep their patients accountable for their sobriety. They rely on BACtrack to provide accurate, consistent results on a daily basis to help keep their members on track, towards a healthy and sober recovery.


Individuals seeking the highest degree of accuracy and consistency from their breathalyzer trust BACtrack to deliver accurate, reliable BAC results for themselves and their loved ones. They gain peace of mind knowing they're helping friends and family make better decisions while drinking.

Why Buy a Professional Breathalyzer?

Precise Results

The linear response of the Xtend® Fuel Cell Sensor Technology inside BACtrack's professional breathalyzers provides precise results over the complete range of alcohol concentrations expected in the breath, from 0.000 to 0.400 % BAC. These models can accurately detect trace amounts of alcohol and reliably handle very high BACs.


BACtrack professional breathalyzers produce the most consistent and reliable BAC 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.  Because of this, these models excel in situations that require multiple high frequency tests.

High BAC Testing

BACtrack professional breathalyzers are consistently more accurate at higher BAC concentrations. If someone is very intoxicated, for example at 0.22% BAC, these models are more likely to provide an accurate test result as compared to semiconductor models, which are often less accurate at higher BAC values.

No False Positives

Unlike some semiconductor models, BACtrack professional breathalyzers will not show a false positive for someone who is diabetic or on a low calorie diet (due to the presence of acetone).
