Abstract

An alcohol-measuring device includes a mouthpiece (1), designed to enable a test subject to release breathing air into the mouthpiece, an electrochemical sensor (6), in fluidic connection with the mouthpiece (1) to measure alcohol in the breathing air of the test subject and a control unit. The sensor (6) has at least two heating elements (9, 10), one heating element arranged on the front side and one heating element arranged on the rear side of the sensor (6). The control unit (4) is electrically connected to the heating elements to supply electrical energy for the heating elements. The control unit (4) is set up to heat the heating elements each to a desired temperature. The control unit (4) is also electrically connected to the sensor (6) in order to determine the value of the alcohol concentration in the breathing air of the test subject.
