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.
Precision Hardware
Thoughtful design, unrivaled accuracy.
Proprietary Sensors
Our professional-grade Xtend Fuel Cell Sensor Technology delivers reliable and accurate BAC results, every time you test.
Mouthpieces
Includes washable, disposable mouthpieces to improve accuracy by collecting the highest quality sample, and to allow you to test others safely.
Internal Breath Pump
Mini solenoid breath pump ensures the most accurate and efficient breath capture for testing.
Accuracy-Focused Engineering
We focus on our technology so BACtrack's pro-grade series consistently outperforms.
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. BACtrack pro-grades can accurately detect trace amounts of alcohol and reliably handle very high BACs.
Consistency
Pro-grade 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. This means pro-grade BACtracks easily handle multiple high-frequency tests.
High BAC Testing
Pro-grade models are consistently 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 less accurate at higher BAC values.
No False Positives
Pro-grade models will not show a false positive due to the presence of acetone, which some semiconductor models misread for someone who is diabetic or on a low calorie diet.
Long-Term Reliability
Extended sensor life helps pro-grade models maintain accuracy for up to thousands of tests, delivering long-term reliability.
Faster Warm Up Time
Pro-grade BACtrack models offer a faster warm-up time, a benefit when conducting high volume and back-to-back tests.
Longer Battery Life
Low power requirements enable up to 1,500 tests on one set of batteries.
