摘要： A gaseous carbon dioxide detection sensor comprising a detection electrode and a reference electrode opposed on both sides of an ionic conductor, wherein a mixture comprising one mol of an alkali metal carbonate more than one mol of an alkaline earth metal carbonate is used as the detection material for the detection electrode. The detection sensor has the electromotive force characteristic relative to the gaseous carbon dioxide less undergoing the effect of moisture in the gas to be measured and has a high sensitivity.

摘要： An oxygen sensor of a limiting current type includes a sensing element coated with a porous coating layer having a catalyst supported thereon. The catalyst includes at least one element selected from the group consisting of platinum, rhodium, palladium, iridium and ruthenium, and the content of the catalyst is not more than 50 wt % with respect to the total weight of the porous coating layer, and particles of the catalyst are dispersed within the porous coating layer at spacings of not more than 6 .mu.m. By using the catalyst, the influence of hydrocarbons to the oxygen concentration is reduced.
