"\r\n\r\n\r\nProprietary Sensor Technology. Unparalleled Precision.\r\nEvery BACtrack breathalyzer is engineered around the two factors that most influence accuracy: sensor type and optimal breath capture.\r\n\r\n\r\n\r\n\r\n\r\nMicroCheck\u00AE Sensor Technology\r\nOur consumer breathalyzers employ Advanced MicroCheck\u00AE Sensor Technology. Using a semiconductor sensor as a base, these sensors go through a patented burn-in process, which delivers more accurate and reliable results when compared to standard semiconductor sensors.\r\n\r\n\r\n\r\n\r\n\r\nOptimal Breath Capture\r\nBreathalyzer 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.\r\nTo enhance accuracy, all BACtrack pro-grade models feature a miniature solenoid air pump to test only air from the deep lungs.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n"^^<http://www.w3.org/2001/XMLSchema#string>
