† DECT (Dynamic Environmental Compensation Technology) enhances the stability and accuracy of our alcohol testers under dynamic environment conditions (varience in temperature and humidity) to avoid false positive readings. DECT also effectively maintains the consistency of reading over time, even after a long period of tester inactivity.
†† EVT (Electronic Valve Technology) automates the sensor to start collecting test sample onlt when a certain air pressure point produced by the blowing action is reached. This enhanced feature borrows the same idea from fuel cell breathalyzers, for the purpose of capturing an air sample from deep in the lungs for accurate measuring.
