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.
Whirling Hygrometer is available in Celsius scale. A guide for Relative
Humidity (RH) determination is supplied with each instrument and the dewpoint
can accurately be obtained using the Dewpoint Calculator.
