Abstract

Electrochemical apparatus for measuring the concentration of oxygen in a liquid alkaline metal that includes: (a) a solid electrolyte body wall conducting the oxygen ions having a pair of opposite side surfaces, the first of said surfaces adapted to be in intimate contact with the liquid metal whose oxygen concentration is to be measured; (b) a mixture that includes a known concentration of one of the metals such as gallium, indium or tin, and an oxide of said metal, said mixture being in liquid state at the operating temperature of said apparatus and in intimate contact with the second of the surfaces of said wall of the electrolyte body to constitute a reference electrode; y (c) a device for measuring any electromotive force generated between said reference electrode and said liquid metal by conducting the oxygen ions through said solid electrolyte to obtain a reading indicative of said oxygen concentration.
