Wet Bulb Temperature Meters - Free Shipping - KestrelMeters.com

These Kestrel Meters measure Wet Bulb Temperature by using a standard mercury-in-glass thermometer, with the thermometer bulb wrapped in muslin, which is kept wet. The evaporation of water from the thermometer has a cooling effect, so the temperature indicated by the wet bulb thermometer is less than the temperature indicated by a dry-bulb (normal, unmodified) thermometer. The rate of evaporation from the wet-bulb thermometer depends on the humidity of the air - evaporation is slower when the air is already full of water vapor. For this reason, the difference in the temperatures indicated by the two thermometers gives a measure of atmospheric humidity.
