The theoretical model which describes the dependence of voltage of the gas phase electrochemical oxygen sensor with a solid oxygenated electrolyte on partial pressure of hydrogen in mixture «argon – hydrogen – water vapor» has been considered. This model has been proved in experiments with gas phase electrochemical oxygen sensor with a solid oxygenated electrolyte with different measuring electrodes and reference electrodes. Experimental results prove the possibility of applying of the gas phase electrochemical oxygen sensor with a solid oxygenated electrolyte for control the content of hydrogen in gas phase of loop of reactors with heavy liquid metal coolants.
