PURPOSE:To obtain a continuously measuring apparatus for CO gas concentration whose operation is stable and reliability is high and which can continuously and correctly measure CO gas in gas to be measured. CONSTITUTION:An apparatus for continuously measuring CO gas comprises an inner electrode 16a made of a non-catalytic electrode for detecting CO gas in gas to be measured, an outer electrode 16b which is made of a porous platinum catalyst attached to an outside of a zirconia tube 1 and to which comparison gas is supplied, a positive contact 2 in contact with a lead of the inner electrode 16a, and a ring-like negative contact 3 made of a non-catalytic metal wire in contact with a lead of the outer electrode 16b. Concentration of CO gas in the gas to be measured is obtained from electromotive force occurring between the inner electrode 16a and the outer electrode 16b. |
