Psychrometric device for measuring gas humidity

摘要

The device (1) includes two temperature sensor s(2,3) placed on a conduit (4) through which a gas flows. The sensors are held at same level by a support (5). One of the sensors 92) is in direct contact with the gas whilst the other (3) is wrapped in a sleeve (6). Water drips from the extremity of a small pipe directly on the sleeve which is thus kept always wet. A string 913) is tied around the sleeve and sensor extremity.
