Whirling Hygrometer

Whirling Hygrometer is a device for measuring the relative humidity of air. There are many physical effects dependent on the amount of water vapor in the air, which have been used to construct hygrometers. A simple form of a hygrometer is specifically known as a "psychrometer".

Established test method for finding the temperature and moisture content of the air prior to painting. Not sensitive to dust / solvent contaminants. BS2842 Mercury Thermometers supplied as standard. Red spirit Thermometers can be supplied if required.

Thermometer scale length = 100mm
Scale division = 0.5 °C
Accuracy +-2%.
