Abstract

A breath alcohol measuring device (7) is provided with features for superior handling especially of the replaceable mouthpiece (1). A direct physical contact between the test subject being tested and the measuring device is practically ruled out by the combination. The mouthpiece (1) of the breath alcohol measuring device (7) has a trapezoidal cross section, which is complementary to a corresponding negative shape in a holder (6) of the breath alcohol measuring device (7) for the flush mounting of the mouthpiece (1).
