ABSTRACT:
A device comprising a combination of a mouthpiece (2) with a holder (1), which receives the mouthpiece (2) and has a sampling channel (4) leading to a breath alcohol-measuring device and a temperature sensor (11) arranged in the connection area between the holder (1) and the mouthpiece (2). To make it possible to determine the temperature of the mouthpiece (2) inserted into the holder (1) the mouthpiece (2) is designed for the temperature sensor (11) to be arranged in the sampling channel (4) as a wall section (10) covering the inner wall of the sampling channel (4) in the area of the temperature sensor (11).
