Because u have to put it in water then spin it around
Relative humidity
psychrometer
The purpose of a psychrometer is to measure the relative humidity in the air. It consists of two thermometers, one of which is wrapped in a wet cloth to measure the effects of evaporation. By comparing the temperatures measured by the two thermometers, the relative humidity of the air can be determined.
A psychrometer is a type of hygrometer used to measure the relative humidity in the air. It consists of two thermometers, one of which is covered with a wet cloth, allowing for the comparison of wet-bulb and dry-bulb temperatures to calculate relative humidity.
Like in a Hygrometer to measure humidity you use percentage (%)
Humidity
A psychrometer is a device used to measure relative humidity in the air. It typically consists of two thermometers – a dry bulb thermometer and a wet bulb thermometer. By comparing the temperature readings from the two thermometers, the relative humidity can be calculated.
No, a psychrometer is utilized to measure the relative humidity in the air by comparing the readings between a dry-bulb thermometer and a wet-bulb thermometer. Wind speed is typically measured using anemometers or other wind-measuring devices.

The sling psychrometer was invented in 1887 by Adolph Richard Assmann, a German meteorologist. It is a simple instrument used to measure the relative humidity of the air.
