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.
During the summer, the dewpoint temperature -- not the relative humidity -- is usually a better measure of how humid it feels outside. It is also a good measure of how much water vapor fuel is available to showers and thunderstorms, with a higher dewpoint representing more water vapor available for conversion to rain.he dew point is always lower than (or equal to) the air temperature. If the air temperature cools to the dew point, or if the dew point rises to equal the air temperature, then dew, fog or clouds begin to form. At this point where the dew point temperature equals the air temperature, the relative humidity is 100%.
