Dew Point Meters - Reviews & Free Shipping - KestrelMeters.com
The Dew Point of air is the temperature at which the water vapor in the air would condense into dew. If this point is below freezing, the dew point is known as the frost point. The dew point determines relative humidity. When the relative humidity is high, the dew point is closer to the current air temperature. If the relative humidity is 100%, the dew point will be equal to the current temperature. As relative humidity falls, the dew point becomes lower, given the same air temperature.
