It consists of 2 glass thermometers containing a liquid.

One measuring instrument measures the air temperature whereas the opposite one measures the wet-bulb temperatures. After the wick is unfit in H2O, a weather observer whirls the sling hygrometer around, using the handle. As the instrument is whirled, water evaporates from the wick on the wet-bulb thermometer and cools the thermometer. The thermometer cools to a very cheap price potential during a jiffy. This value is known as the wet-bulb temperature. The drier the air the additional the measuring instrument cools and therefore, the lower the wet-bulb temperature.
