Abstract:
A gas measurement device for measuring the concentration of a plurality of gas components by means of absorption measurement comprising a light source for infrared radiation (3) or a thermal radiator (4) as a light source (5), an optics (22) for bundling the light of the light source (5), a band pass filter (4) and a photoacoustic measurement cell (12) for measuring a plurality of gas concentrations, wherein a Fabry-Perot filter (6) is provided in front of the photoacoustic measurement cell (12) in addition to the band pass filter (4) for selecting the absorption spectra.
