The Model 116 Whirling Hygrometers use a manual technique to measure Relative
Humidity (RH) and dew-point. These instruments consist of two thermometers, the
bulb of one being covered by a wick. The wick is saturated with water and the
hygrometer whirled for about 90 seconds. RH and dew-point are then calculated from
the wet and dry bulb temperature readings using the guide or the Elcometer 114
Dewpoint Calculator.
The Model 116A (spirit) and Model 116B (mercury) Whirling Hygrometers are available
in either Celsius or Fahrenheit scales. A guide for Relative Humidity (RH)
calculation is supplied with the instruments. Use the 116B mercury filled
thermometer whirling hygrometer in accordance with BS 2842 test methods.
