HYGROMETER
Abstract
This pntent relates to a hygrometer having a rapid and essentially straight line response to changes in relntive humidity and a high degree of sensitivity to moisture in the low relative humiaity range. In particular, the hygrometer comprises a metal plate coated with a hygrometric oxide coating, and electrical leads coupled to the metal plate and the oxide coating, respectively. When a change in relative humidity occurs, a change in the resistance and capacitance between the leads takes place owing to the hygrometric action of the oxide coating. Thus, with a voltage being applied to the leads, a change in capacitance and resistance between them causes a proportional change in the current between the leads. This may be read upon a suitable indicator for determining the relative humidity at any given instant. (AEC)
