The paper presents results on the use of iron oxide reference electrode in the oxygen activity sensors used to measure the oxygen activity in heavy liquid metal coolants. The specific features of the operation of the sensor with iron oxide reference electrode are established and comparative characteristics with respect to other applicable reference electrodes are presented. Conclusions on the reasonability of its use for measurement of oxygen activity in liquid metal media are drawn.
