Electric humidity detecting sensing element on the basis of a layer of porous aluminum oxide, treated by sealing in boiling water, passivation and tempering at 70 DEG to 110 DEG C., achieving thereby a substantial reduction of subsequent variations of calibrating curves. The time of tempering may ra...
