Law Enforcement-Grade Accuracy

The S75 Pro can be depended on to provide accurate BAC readings in situations that require the most reliable results. The Department of Transportation has approved the S75 Pro for its reliability and accuracy. By providing 4-digit test results, the S75 Pro can pick up even trace amounts of alcohol as low as 0.001% BAC, necessary in zero-tolerance environments where subjects may have consumed only a small amount of alcohol.

Xtend® Fuel Cell Sensor Technology

The BACtrack S75 Pro uses highly-accurate Xtend Fuel Cell Sensor Technology, and can be used for professional and medical testing applications. Benefits include:

  • Consistent Results – The linear response of Xtend Fuel Cell Sensor Technology provides the most accurate results over the complete range of alcohol concentrations expected in the breath, from 0.000 to 0.400 %BAC.
  • Long-term Accuracy – A single set of AA batteries deliver up to 1,000 tests.
  • Highly Reliable – Enjoy long-term reliability with long sensor life.
  • Acetone Resistant – Unlike semiconductor-based breathalyzers, S75 test results are not influenced by acetone, which may be present in individuals with diabetes.
