How do we measure relative humidity
WebRelative humidity tells how much water vapor is in the air relative to the amount it has the potential to hold at a given temperature and pressure. The instrument used to measure water vapor content in the air is called a hygrometer. WebApr 10, 2024 · Understanding the Concept of Relative Humidity. The relative humidity is a measure of the amount of moisture in the air compared to the maximum amount the air can hold at a given temperature. It is expressed as a percentage. To better understand relative humidity, we must first differentiate it from two other humidity concepts: Absolute ...
