Abstract
Apparatus for the detection of carbon monoxide concentration of a gas. The apparatus comprises a base from which a pair of arms extend, a resistance layer disposed on each arm serving both to measure the difference in temperature between the arms and to heat a catalyst layer; a protective layer on the resistance layers to prevent electrical shorts caused by deposit of conductive particles in the gas to be detected; and a catalyst layer on one and only one of the arms in contact with the protective layer.
