When allowed to react with ZnO at 873 K, H2S-H2 gas mixture turns into H2O-H2 gas mixture almostcompletely. The H2O/H2 gas ratio, which should correspond to the H2S/H2 ratio in the gas mixture originally passed, canbe evaluated from the emf measurement utilizing an oxide solid electrolyte. The effectiveness of the H2S/H2 gas sensor, basedon this principle, has been shown experimentally in the present investigation. As an example of the applications, the sulfurpartial pressure exerted by Ag-Ag2S two melts was measured by using this H2S/H2 gas sensor. The present experimental results werefound to be in reasonable agreement with the published values.
