Abstract :
The basic element of this hygrometer is an alumina core saturated with a chemical solution which will absorb atmospheric moisture and so become electrically conductive. Functioning on 120-volt a-c supply, it will give enough current to operate an a-c relay between relative humidities of 20 to 100 per cent.
