ABSTRACT:
A solid state reference electrode which is stable over a wide range of temperatures, pressures and chemical conditions is provided. The subject reference electrode comprises a zirconia or yttria stabilized zirconia tube having a distal, closed end and a proximal, open end. An opening in the distal end of the tube provides for ionic conduction between the electrolyte inside of the tube and fluid outside of the tube. Inside the tube is an electrolyte containing zirconia, alumina, potassium chloride and silica. Positioned in the electrolyte composition, near the proximal end of the zirconia tube, is a sensing element. A sealing means at the proximal end of the tube seals the inside of the tube and connects the tube to a stainless steel casing. An electrical lead extends from the sensing element through the sealing means. The electrode comprises means for maintaining a constant temperature in the region of the electrolyte composition occupied by the sensing element.
