An exhalation air analysis device, in particular for alcohol analysis including a flow duct coming from the tested person to a testing housing having a movable duct element with a recess. The duct element can be adjusted in two different settings in the housing. In the first position the recess is connected to an inlet and outlet of the exhalation air line, so that the recess forms a part of the flow duct of the exhalation air. In a second position of the duct element, its recess is cut off from the flow duct and connected to a detector. The volume of the recess forms a part of the analysis chamber required for the analysis.
