A psychrometer is used in measuring temperature to determine relative humidity (RH). It consists up two thermometers that read both wet and dry temperatures at 0.1 degree celsius increments.
A psychrometer measures relative humidity using two thermometers: a dry-bulb thermometer and a wet-bulb thermometer. The difference in their readings allows the calculation of humidity levels in the air. It is commonly used in meteorology, agriculture, and HVAC industries.
