    Basically you put two old-style thermometers next to each other. One has a conventional ‘dry’ bulb. The other has damp gauze or something similar wrapped around the bulb.

    In low humidity conditions, the wet bulb thermometer will read considerably cooler as the evaporating water cools the thermometer

    At 100% humidity the two thermometers will read the same, as no water will be evaporating.
