Unlike relative humidity, dew point measurement is independent of temperature. However, when measuring dew point, pressure conditions must be taken into account. Beware of Temperature Differences When mounting a humidity probe into a process, avoid temperature drops along the probe body.
Define Dew Point: Now the good part: the dew point (Tdp) is the temperature at which water vapor just starts to condense out of air that is cooling-for example when warm moisture-laden air contacts a cool surface inside of a wall cavity. Above the dew point the moisture stays in the air.he curved relative-humidity lines intersect with the diagonal lines to show the dew point for various temperatures and levels of relative humidity. Dry bulb (Tdb) temperature (chart bottom or x axis) is just the measured indoor temperature measured using a standard thermometer.
