MEASURING DEVICE FOR OPTICAL DETERMINATION OF TOXIC GAS CONCENTRATION BY TRANSMISSION |
摘要 |
The aim of the invention is to produce a measuring device by means of which the concentration of a toxic gas can be rapidly and simply determined. According to the invention, said aim is achieved by means of a measuring device for optical determination of the concentration of at least one toxic gas by transmission, comprising a measuring cell which is not transparent to light, with a housing in which a tubular at least partly transparent detection means, at least partly provided on the inner wall thereof with a transparent coating of a given layer thickness made from at least one polymeric material with at least one indicator substance immobilised therein, further comprising a pump or suction device arranged before or after the detection means, which pumps a toxic gas stream through the detection means and at least one light source and at least one receiver means arranged to one and/or more sides of the detection means, by means of which an absorption change for the indicator substance is measured by transmission as a function of time. The receiver means may be connected to an analysis unit. |
