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