Abstract
PURPOSE:To attain high quality while achieving measurement in a short time with high precision, by reducing the capacity of a generation space for reference gas by stacking diaphragms of plane electrolyte and by interposing a prescribed conductive substance between the stacked surfaces. CONSTITUTION:A diaphragm 1 which has electrodes 5 and 6 on both plate surfaces of a plane solid electrolyte and a diaphragm 2 which has electrodes 7 and 8 on both plate surfaces of a plane solid electrolyte having a fine through hole 3 in the thickness direction are so stacked that the plate surfaces face mutually; and annular conductive foil 4 is interposed between their stacked surfaces to joint both the diaphragms 1 and 2 in one body with the conductive foil 4. Then, a DC current with a prescribed value is flowed between the electrodes 7 and 8 to substitute a small-capacity space 9 with reference gas. In this state, gas to be measured is brought into contact with the electrode 5 to generate electromotive force between the electrodes 5 and 6. This electromotive force is measured to obtained the oxygen concentration of the measured gas.
