That one of the two similar thermometers of a psychrometer the bulb of which is moistened; also, the entire instrument.
Thermometer on a psychrometer that has a moisten wick on its reservoir bulb. When ventilated this thermometer records a temperature that is modified by the cooling effects of evaporation. This measurement and the temperature reading from a dry-bulb thermometer are then used to determine the air's relative humidity or dew point from a psychrometric table.
In a psychrometer, the thermometer that has the wet, muslin-covered bulb, and, therefore measures wet-bulb temperature.
a thermometer with a bulb that is covered with moist muslin; used in a psychrometer to measure humidity
a thermometer that measures the relative humidity in the air, based on the heat extracted by evaporation of water on a cloth thermometer bulb.
(or wet-bulb) The thermal sensor in a psychrometer that has a muslin covered bulb which is saturated with water and then ventilated thoroughly to attain the wet-bulb temperature. Contrast with dry-bulb thermometer.
A thermometer with a muslin-covered bulb which is moistened. Used to measure wet-bulb temperature.
Instrument that takes the measurement of water vapor in the air. The water-saturated cloth wick over the reservoir bulb at the end of the tube, which holds the liquid. When the thermometer is swung through the air, the 0evaporation of the water in the wick speed up and the temperature recorded varies depending on the water vapor in the air. It determines humidity when used along with a dry-bulb thermometer and a calibration chart.
