Used for court systems, trucking companies, taxi companies, etc. The only smartphone breathalyzer app that employs police-grade Xtend® Fuel Cell Sensors, the same advanced technology trusted by hospitals, businesses, schools, and even law enforcement. Pro-grade models are consistently accurate at higher 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 values. Extended sensor life helps pro-grade models maintain accuracy for up to thousands of tests, delivering long-term reliability. Low power requirements enable up to 300 tests on one battery charge.
