Abstract
A method and a device monitors the quality of gaseous media dispensed by a filling station, in particular hydrogen, by an infrared measuring system. The infrared measuring system is connected into the dispensing path of the respective gaseous medium extending from the filling station to a consumer, and measures the transmission of infrared radiation at different wavelengths and different pressures. From the transmission measurements, the concentration of contaminants, which influence the quality, is calculated. At least when predetrminable quality parameters are exceeded, this exceeding is indicated.
