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.

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.

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.

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.

Extended sensor life helps pro-grade models maintain accuracy for up to thousands of tests, delivering long-term reliability.

Pro-grade BACtrack models offer a faster warm-up time, a benefit when conducting high volume and back-to-back tests.

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