Elcometer 116 Whirling & Sling Hygrometer
The Elcometer 116 Whirling and Sling Hygrometers are designed to determine the dew point and relative humidity (RH) at
any given time.
The Elcometer 116A 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 calculated using the Elcometer 114 Dewpoint Calculator.
The Elcometer 116C Sling Hygrometer, shown as the black unit in the photograph, is a convenient, self-contained
instrument with an inbuilt slide rule for the calculation of %RH and dewpoint. This hygrometer has spirit filled thermometers
and is available in °C or °F scales.

Manual operation, no power supply required
•
Spirit filled thermometers
Test Method and Operation
Hygrometers use a manual technique to measure Relative Humidity (RH) and dewpoint.
These instruments consist of two thermometers, the bulb of one being covered by a wick. The wick is saturated by filling
the plastic container with water. Hold the Hygrometer by the handle and whirl through 360º facing the wind or any airflow
for about 90 seconds.
This is repeated until the wet bulb thermometer cools down to a constant frame temperature and two consecutive pairs of
readings agree.
The RH and dewpoint are then calculated from the wet and dry bulb temperature readings using the Dew Point Table or
the Elcometer 114 Dewpoint Calculator. Ensure the wet bulb wick dips into the small water container attached to the
Hygrometer frame. Check the water level each time before using.
