Wet-Dry Bulb Hygrometer

  • Used to calculate the water vapor content (relative humidity) of air at a given temperature.
    • The instrument is made up of two identical thermometers, one a wet bulb, and the other a dry bulb. The wet bulb thermometer has it s bulb wrapped in a tight fitting muslin cloth material (wicking) which is soaked in water. When the thermometers are ventilated the wet bulb temperature will be lower than the dry bulb temperature.

      Subtracting the wet bulb reading from the dry bulb reading yields the Wet Bulb Depression. The relative humidity can now be read from the table provided.
