Humidity meters (Hygrometers)

 

Humidity is the amount of water vapor in the air. Water vapor is the gas phase of water and is invisible.[1] Humidity indicates the likelihood of precipitation, dew, or fog. Higher humidity reduces the effectiveness of sweating in cooling the body by reducing the rate of evaporation of moisture from the skin. This effect is calculated in a heat index table, used during summer weather.

There are three main measurements of humidity: absolute, relative and specific. Absolute humidity is the water content of air.[2] Relative humidity, expressed as a percent, measures the current absolute humidity relative to the maximum for that temperature. Specific humidity is a ratio of the water vapor content of the mixture to the total air content on a mass basis.
