Abstract

A gas sensor (100) in a sensor housing (1) has a gas-permeable membrane (7) for the inlet of a gas sample to be analyzed to a measuring electrode (6). The gas sensor (100) is provided with a test gas generator (18), which has a generator housing (8). The generator housing (8) is fastened in the area of the gas-permeable membrane (7) and has a central gas outlet opening (21) for the gas sample to pass into the sensor and has outlet openings (19) directed towards the gas-permeable membrane (7) for the test gas.
