Abstract

The gas-analyzing apparatus described in Specification 124,453, in which a pair of electrically-heated wires forming part of a wheatstone bridge are for comparison surrounded by the gas to be tested and a standard gas, is provided with means whereby both of the gases are saturated at the same temperature with an extraneous constituent such as water vapour, in order to eliminate the errors arising from the presence of such constituent. In the case of flue gases, the apparatus is adapted to eliminate the effect of water vapour by enclosing in the cavity containing the standard gas an excess of water, and by cooling the apparatus or the gases so that when under test the latter are saturated with water vapour.
