A zirconia membrane electrode which responds to pH can serve admirably as a pH sensor in high temperature aqueous systems. Alternatively, under conditions of known, stable pH the sensor may be used as a reference electrode for monitoring corrosion and redox potentials. Examples are given of such applications including correlations with related ambient temperature measurements of pH, oxygen and hydrogen concentrations, and water resistivity.
