The electrical resistance dew point hygrometer has the sensitive part of an electrical resistance hygrometer placed in a small case provided with two pipes. The gas to be measured is let in through one pipe and out through the other. If the relative humidity of the gas is too low to measure, the gas is cooled from outside of the case and if too high, the gas is heated. Dew point of a gas is not altered by changing the temperature if the pressure is made to remain constant.
