EASY ASSEMBLY || 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
EASY OPERATION || Once assembled the user swings the apparatus for 30 seconds then records the temperatures on both the wet-bulb and dry-bulb
PSYCHROMETRIC CHARTS || Relative humidity and dew point are determined by comparing the temperature difference between wet and dry bulb readings against the included psychrometric charts
GREAT FOR STUDYING WEATHER || The interactive, hands-on Sling Psychrometer promotes student understanding of meteorology and weather
This kit is easily assembled by attaching the 2 thermometers to the end of the handle and placing the moisture cloth over the wet bulb. Once assembled the user can swing the apparatus and then read the difference in temperature between the web-bulb and dry-bulb to determine the relative humidity. After a few minutes spinning the apparatus the user can take the temperature readings and review the psychometric chart to determine relative humidity
