August-pattern psychrometer


A psychrometer is a 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 prior to an observation. When the bulbs are suitably ventilated, they indicate the thermodynamic wet- and dry-bulb temperatures of the atmosphere. Our instrument has a brass holder, for the two glass mercurythermometers and the water reservoir, and a turned beech wooden base. 65cm high.
