ABSTRACT:
A moisture-sensing hygrometric element is provided comprising an electrolytic moisture-sensing mechanism integrally formed on the surface of a porous substrate, the porous substrate being resistant to oxidation and reduction and resistant to acids, wherein the moisture-sensing mechanism comprises a pair of platinum group metal electrodes constituting an anode and a cathode and having a fluororesin-type cation exchange resin membrane layer thereover. The porous substrate may be porous ceramic or a porous fluororesin such as expanded polytetrafluoroethylene. The hygrometric element may have an additional covering layer thereover of porous, expanded polytetrafluoroethylene. Also provided is a method for manufacturing the moisture-sensing hygrometric element.
