Details:

The 7-piece Sling Psychrometer Kit contains: one dry bulb thermometer (6.5 inches long), one wet bulb thermometer (6.5 inches long), one wooden handle (5 inches), one cloth sleeve, one screw, two rubber bands, and one instruction guide. The apparatus is easily assembled by attaching the two thermometers to the end of the handle and placing the moistened cloth sleeve over the wet bulb. Once assembled, the user swings the apparatus for 30 seconds and then records the temperatures on both the wet-bulb and dry-bulb thermometers. Relative humidity and dew point are determined by comparing the temperature difference between the wet- and dry-bulb readings against the included psychrometric charts found in the instruction guide. This interactive, hands-on Sling Psychrometer promotes student understanding of meteorology and weather.
