The invention relates to a gas measuring system, containing at least one gas sensor (1) and at least one gas generator (4), whereby the gas sensor (1) has at least one measuring area (3), at which a target gas concentration can be measured, the gas generator (4) has at least one exit area (5), from which a flow-proportional test gas quantity can emerge, whereby the measuring area (3) and the exit area (5) are designed in such a way and the gas sensor (1) and the gas generator (4) can be arranged in such a way that the measuring area (3) and the exit area (5) are in direct contact with the ambient atmosphere and the distance between the two areas is smaller than the extension of the smaller of the two areas. The extension of the area means, depending on the shape of the area, a characteristic length, for example the diameter or a side length which can be used to describe the size of the area.
