Breath alcohol measurement with contactless sample provision

The invention relates to a device for breath alcohol measurement, having a sample collector (1) into which a breath sample can be introduced via a sample inlet (2) by the test person. The device has a measurement unit (9) having a sensor (16) which is situated therein and to which some of the breath sample provided into the sample inlet (2) can be supplied. Said measurement unit generates a measurement signal on the basis of an alcohol content in the breath sample. A control and evaluation unit (4) is also provided, which determines the alcohol content of the breath sample on the basis of the measurement signal and transmits a result-specific signal to an output unit (5) which provides information about the breath alcohol content of the breath sample. The described technical solution is characterised in that: the sample collector (1) and the sample inlet (2) are designed to be suitable for contactless introduction of the breath sample; adjoining the sample inlet there is a main flow duct (10) which runs at least partially within the sample collector (1) and from which some of the breath sample provided into the sample inlet (2) is applied at least intermittently to the sensor (16) via a measurement gas duct (21) and which opens into the environment (7) via an outlet downstream of the measurement gas duct (21) in the flow direction; and between the sample inlet (2) and the outlet of the main flow duct (10) there is at least one further outflow opening (6) through which some of the breath sample introduced into the sample inlet (2) exits into the environment (7).
