DÉFINITION
- A psychrometer is an instrument used for measuring the water vapor content of the atmosphere; a type of hygrometer. It consists of two thermometers, one of which (the dry bulb) is an ordinary glass thermometer, while the other (wet bulb) has its bulb covered with a jacket of clean muslin, which is saturated with distilled water before an observation. When the bulbs are suitably ventilated, they indicate the thermodynamic wet- and dry-bulb temperatures of the atmosphere. One variety is the Assman psychrometer (a special form of aspiration psychrometer for which the ventilation is provided by a suction fan).
