Abstract
PURPOSE:To simplify the mechanism of an air pollution measuring apparatus and facilitate the handling thereof, by connecting to a supply pipe for an air pollutant absorbing liquid a cell formed an air-permeable film wall capable of preventing said air pollutant-absorbing liquid from oozing out, and exposing said cell to the polluted air. CONSTITUTION:The absorbing liquid 2 in an absorbing liquid reservoir 1 is sent to both a reference light absorbance-measuring cell part 5' and light absorbance-measuring cell part 5 through a duct 3 by means of a pump 4 before flowing out into a waste liquid reservoir 6. The light absorbance-measuring cell 5 is formed from an air-permeable film wall 5'', made of such material as polypropylene, polytetrafluoroethylene or the like, having water repellent fine holes and preventing the absorbing liquid 2 from oozing out, and the periphery thereof is exposed to the polluted air. The pollutant in the atmospheric air is passed through the air-permeable film wall 5'', absorbed in the absorbing liquid 2, and the coloring degree of the absorbing liquid is detected by means of an optical detector 9. The representative of the difference between said detection signal and the detection signal from a reference optical detector 9' is sent to a recorder 11 from an amplifier 10.
