FIELD: measurement equipment.
SUBSTANCE: solid electrolyte sensor for amperometric measurement of hydrogen and oxygen concentration in gas mixtures comprises a disc from solid electrolyte with oxygen conductivity, two electrodes applied onto opposite surfaces of this disc, a disc from a proton-conducting solid electrolyte with two electrodes applied on its opposite surfaces, and a capillary, both discs and the capillary are tightly connected to each other, and between the discs the sensor has an inner cavity.
EFFECT: possibility of simultaneous measurement of hydrogen and oxygen concentration in a gas mixture, simplified design of a sensor and its increased efficiency.
