Abstract: A breath alcohol measurement device has a sample collector (1) with a sample inlet (2) configured for a contactless introduction of a breath sample. A measurement unit (9) has a sensor (16) that generates a measurement signal based on an alcohol content in the breath sample. A control and evaluation unit (4) determines the alcohol content based on the measurement signal and transmits a result-specific signal to an output unit (5). Some of the breath sample provided into the sample inlet (2) is applied, at least intermittently via a main flow duct (10), to the sensor (16) via a measurement gas duct (21) that is connected via an outlet to the environment (7). Between the sample inlet (2) and the outlet of the main flow duct there is a further outflow opening (6) through which some of the breath sample introduced into the sample inlet exits into the environment.

A measuring module (11) transdermally detects measured values of the alcohol concentration (TAK) in the test subject (2). A transmission module (12) transmits the measured values to a relay station (20) having a receiving module (21), receiving measured values from the transmission module (12) and a sending module (22), sending received measured values to a remotely located monitoring station (30). An energy storage device (13, 23) provides an energy supply of the measuring module (11) which is uncoupled from the energy supply of the relay station (20).
