when was the sing psychrometer invente
it has changed a lot
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
It is used for finding the dew point of the atmosphere. It combines a wet and dry thermometer in one unit.
when was the sing psychrometer invente
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.

It measures humidity
A
Relative humidity
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.
it has changed a lot
The temperature and dewpoint of the air (degrees), eventually indicating the relative humidity (percent). Both are dimensionless numbers ... they have no units.
Like in a Hygrometer to measure humidity you use percentage (%)
One of the better ways would be to use a sling psychrometer.
