The new BACtrack Element quickly and easily tests for the presence of alcohol and provides a blood alcohol content (BAC) estimate. Simply press power, blow through one of the included mouthpieces, and get results in seconds. The Element uses professional Xtend fuel cell sensor technology, which provides consistent, accurate results at both low and high BAC levels. The spring-activated pump ensures that a proper breath sample is taken and that results are consistent test-to-test. Because the BACtrack Element uses AAA batteries, it is smaller and lighter than any other full-featured fuel cell breathalyzer available. This makes it easier to carry in a pocket or keep in a car and makes it easier to use on a regular basis. In addition to the Xtend fuel cell technology, the Element incorporates improved temperature compensation software to provide increased performance in both cold and hot environments. The bright four-digit LCD display shows blood alcohol content results from 0.000 to 0.400% BAC in an easy to read format. The Element is FDA 510(k) cleared for personal use, and is also used by clinics, businesses, hospitals and even law enforcement as an alcohol screening device. The BACtrack Element breathalyzer is simply a superior combination of accuracy, affordability, and design.
