The Armstrong Humidification Handbook

Humidity and Temperature Humidity is water vapor or moisture content always present in the air. Humidity is definable as an absolute measure: the amount of water vapor in a unit of air. But this measure of humidity does not indicate how dry or damp the air is. This can only be done by computing the ratio of the actual partial vapor pressure to theGet price

Relative Humidity Measurement System
