Condensing Humidity (dew point) Calculator

The Condensing Humidity Calculator (Dew Point Calculator) is used for rapid calculation of surface dew points (i.e. relative humidity above which there is condensation probability on the surface) resulting from the input of surface and space air temperatures.

Space Temperature: The temperature of the space air.

Surface Temperature: The temperature of the surface under consideration

Condensing Humidity: The resulting dew point (maximum safe relative air humidity)

The formulas used for this dew point calculation are defined in the by formulas of partial pressure as shown in the EN ISO 13788:2002.
