Hygrometer
A hygrometer is a scientific instrument used to measure the amount of humidity in the air. It is an important tool in meteorology, agriculture, and industrial processes where controlling humidity is crucial.
Types of Hygrometers
- Psychrometer: This type of hygrometer uses two thermometers, one of which is dry and the other is covered with a wet cloth. The difference in readings between the two thermometers is used to calculate the relative humidity.
- Electrical Hygrometer: These hygrometers measure humidity using electrical properties of certain materials, such as changes in resistance or capacitance.
- Dew Point Hygrometer: This type measures the temperature at which dew forms on a surface, which is used to calculate the relative humidity.
