Psychrometers / Mason Hygrometers

A sling psychrometer measures the amount of water vapor in the air or humidity. The sling psychrometer consists of two glass thermometers and a wick. One thermometer measures the air temperature while the other one measures the wet-bulb temperatures. Wet bulb temperature is the lowest temperature that can be obtained by evaporating water into the air at constant pressure. The wick is dipped in distilled water, and the sling psychrometer is whirled around, using the handle. As the instrument is whirled, water evaporates from the wick are spun on to the wet-bulb thermometer and cools the thermometer. The drier the air the more the thermometer cools and hence, the lower the wet-bulb temperature. The user then converts the measurements using a table to get the relative humidity. Mason's Hygrometer is actually a wet and dry bulb thermometer pair that tells you the temperature and relative humidity in any indoor location where the temperature remains above freezing. The humidity indication is based on the difference between the wet and dry bulb temperatures. Humidity calculator is used for the rapid conversion of humidity measurements. If you have questions about a sling psychrometer contact a Davis Application Specialist.
