The sling psychrometer is a device that uses the wet/dry bulb method where the thermometers are attached to a handle or length of rope and spun around in the air for a few minutes. A psychrometer is a device that consists of two thermometers, one of which includes a dry bulb and one of which includes a bulb that is kept wet to measure wet-bulb temperature.
