Wet-Bulb Temperature The temperature measured by a temperature sensor on which a wet
cloth has been draped. Is is used to measure humidity. Relative humidity
is calculated from this temperature and the air temperature measured by
a dry-bulb sensor.
Wet-Bulb Wick The cloth draped over a wet-bulb temperature sensor. It absorbs water
and keeps the sensor wet. Though gauze is used in meteorological appli-
cations, a woven cloth is used inside an environmental chamber because
of its strong resistance to heat and cold.
