A device has at least one sensor for determining one or more constituents of a medium flowing in an installation duct. The device has a housing and a main channel, which is connected to said housing and is closed at an end remote from the housing. The main channel has a first channel and a second channel, which is separated from the first channel by a first separating wall. The main channel also has at least one first opening, which is away from the end and creates a first connection between the first channel and the installation duct, and at least one second opening, which is away from the end and creates a second connection between the second channel and the installation duct, so that the medium flows between the openings, through the channels and past the sensor.
