The sampling system allows short measurement intervals and shortest waiting times between measurements and controls and records the exhaled air volume during sampling and detects any attempt at deception. Due to its high precision, this breathalyzer is also used by the police: Everyone who ever got into a traffic control with an alcohol sample in Austria already had contact with this breathalyzer. The operation is very simple, there are three buttons available for this purpose. The switch-on button is located in the middle of the device and is therefore equally easy to grasp for left-handed and right-handed users. Switch on, blow, wait for the display, switch off, done. Alcohol measurement could hardly be simpler.
