Abstract:
1. A gas-measuring system comprising: a gas sensor with a measuring surface, with an ambient atmosphere side, at which a target gas concentration, at the atmosphere side, is measured, said measuring surface having a maximum measuring surface dimension of an area of said measuring surface; a gas generator with a discharge surface, with an ambient atmosphere side, for discharging a quantity of test gas to the atmosphere side, said discharge surface having a maximum discharge surface dimension of an area of said discharge surface, said measuring surface and said discharge surface being in direct contact with ambient atmosphere, at the atmosphere side, with a distance between said measuring surface and said discharge surface being smaller than each of said maximum measuring surface dimension and said maximum discharge surface dimension, wherein: said gas sensor and said gas generator each a form planar assembly unit, with the units brought flatly into contact with one another; and said measuring surface is arranged ring-shaped, around an opening in said gas sensor and said discharge surface is arranged behind said opening with said gas sensor and said gas generator brought into flat contact with one another.
