Sling Psychrometer
Relative Humidity Meter

Part No. 12-7012
Sling psychrometers are known for great accuracy, dependable results within about 90 seconds, and independence from batteries. The procedure is simple enough: wet the wick, swing the instrument until the wet bulb reading goes no lower, then take the wet-bulb and dry-bulb readings to the tables or slide rule supplied to determine relative humidity. It's a traditional and always reliable process. When not in use, the thermometer case telescopes into the handle for protection.
