Urbonavichute UDC 622.411 Route and time studies of air in the pits and mines of the "Vorkutaugol' " Combine and Magadan have re- vealed that the relative humidity varies from 30 to 100%, the temperature from +15 to -3YC, and the air current speed from 0.2 to 4 m/sec. These quantities can be used to determine the main requirements of an apparatus for remote humidity control. The apparatus must, of course, be able to operate in dusty conditions and must be "in- trinsically safe" (free from explosion hazard). In this article we will briefly report on some work at the Leningrad Mining Institute, aimed at designing such an apparatus. In the Soviet [1, 2] and foreign [3, 4] literature, it is stated that the most promising developments in this di- rection are condensation hygrometers with semiconducting coolers and automatic condensate-layer control, and electrolytic hygrometers with sodium-potassium chloride sensors of the DVV type [5]. In developing a condemation hygrometer at the Leningrad Mining Institute, we took as a basis the M-57A hygrometer [61 whose main units satisfy the requirements for measuring mine air humidity. The M-57A hygrome- ter does not give a direct reading
