Abstract

A device for indicating the presence of constituents in a gas mixture, particularly hydrogen sulphide in coal gas, comprises a gas tight chamber 10 having transparent sides and containing a piece of test paper or like absorbent material, and means for passing a ray of light of variable intensity through the chamber to a photo-electric cell 11 which operates an indicating device. The chamber 10 is preferably a cylinder of which one face 33 can be unscrewed to renew the test paper, which may be mounted on small prongs 36, 37. The <PICT:0426378/III/1> <PICT:0426378/III/2> adjustment of the source of light is preferably effected by sliding it along a bar 30. The gas under test may be burned to supply the light.
