Guidance for Operating and Storage Environments
Dew points indicate the amount moisture in the air. The higher the dew point, the higher the moisture
content of the air at a given temperature. Dew point temperature is defined as the temperature to which
the air would have to cool (at constant pressure and constant water vapor content) in order to reach
saturation. A state of saturation exists when the air is holding the maximum amount of water vapor
possible at the existing temperature and pressure
