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!
