Sling Psychrometer Kit - Determine Relative Humidity & Dew Point

This Sling Psychrometer Kit provides a hands-on method for determining relative humidity and dew point. The seven-piece kit includes a dry bulb thermometer (6.5"), a wet bulb thermometer (6.5"), a 5" wooden handle, a cloth sleeve, a screw, two rubber bands, and an instruction guide with psychrometric charts. Assembly involves attaching the two thermometers to the handle and placing the moistened cloth sleeve over the wet bulb. The user swings the assembled apparatus for 30 seconds, then reads the temperature difference between the wet and dry bulbs. Relative humidity and dew point are determined by comparing readings against the included psychrometric charts.
