Stabilized zirconia is a solid electrolyte with good oxygen ion conductivity, two electrodes are provided on both sides of the stabilized zirconia, and one of the electrodes is covered with a fine diffusion hole. a lid, the limiting current generated in a predetermined region of the voltage applied to the electrode is proportional to the oxygen concentration around the electrode, and the combustible gas is burned by the high temperature of the electrode and the catalytic action of the electrode material. In the limiting current type oxygen sensor, the first voltage is a voltage smaller than the theoretical decomposition voltage of water such that the limiting current depends only on the residual oxygen after combustion, and the voltage generated by the combustion of the residual oxygen and combustible gas is set as the first voltage. A voltage higher than the theoretical decomposition voltage of water, which depends on water vapor, is applied to the second
The first voltage and the second voltage are alternately switched and applied between the electrodes as a voltage, and the first voltage and the second voltage are applied between the electrodes.
A combustible gas measuring device characterized by comprising an arithmetic circuit that holds each voltage input from the electrodes and detects combustible gas.
