Loss of heat of evaporation from the wet bulb. (The reason you "sling it around" is to speed up the evaporation.)
The antonym of psychrometer is thermostat

The purpose of the psychrometer is to estimate Relative Humidity of Air. It does it by getting the dry and wet bulb temperatures. Then Relative Humidity is read on a chart.
Leonardo da vici (the artist) built the first crude hygrometer in the 1400s and francesco folli invented a more practical hygrometer Leonardo da vinci
A sling psychrometer (which is a hygrometer) measures the moisture content of the atmosphere surrounding it. It is called a sling psychrometer because it is whirled around in the air until a constant value/reading is obtained from the wet-bulb thermometer.

There are a lot of places to buy a sling psychrometer. Any company which sells scientific equipment should have them, or one could buy it from Amazon or Bacharach.

One of the better ways would be to use a sling psychrometer.
There are two types - the wet-bulb sling psychrometer and the dry-bulb psychrometer. Look up the definitions of these instruments for more details.
psychrometera hygrometer would be useful!
