Abstract
An improved flow-through electrolytic hygrometer is provided which utilizes a long lasting oxidation-resistant, hollow fiber formed of a persulfonic acid substituted polytetrafluoroethylene having closely spaced noble metal electrodes in contact with the inner and outer surfaces of the fiber. The fiber is disposed within a chamber such that the moisture-bearing gas passes in contact with at least one surface of the fiber. The electrodes are connected in series to a DC voltage supply and an ammeter. As the gas passes through the chamber, moisture absorbed into the wall of the fiber is electrolyzed to hydrogen and oxygen by the closely spaced electrodes. The amount of electricity required for electrolysis is proportional to the absorbed moisture and is observed on the ammeter.
