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
