ABSTRACT:
An improved solid state electrode system for measuring the pH of fluids at temperatures as high or even higher than that corresponding to the critical point of water (374.2.degree. C.). A stabilized metal oxide based ceramic member having a predetermined thickness is coupled to a first metallic conductor by a uniform, solid oxygen-free electrolyte to serve as a pH sensing electrode. A body of an electrochemically inert material, which preferably comprises a stabilized metal oxide based ceramic member having a lesser thickness or a greater porosity, is coupled to a second metallic conductor by a similar uniform solid electrolyte to serve as a reference electrode. Together the pH and reference electrodes form an electrode system that is suitable for use in applications in which the temperatures and/or pressures of the test solution preclude the use of conventional electrodes. A variety of configurations and compositions are disclosed which allow the electrode system to be fabricated in an improved manner.
