Sling Psychrometer Kit
Available as individual kits or a classroom set of 15. Recommended
for students in grades 6 through 12.
|Measure relative humidity with this simple sling psychrometer.
Each psychrometer contains a wet and dry bulb Celsius thermometer
that rotates on a plastic handle. Students swing the psychrometer
to determine the temperature difference between the wet and dry
bulbs (wet bulb depression). The relative humidity can be
determined by using a standard graph showing the intersection of
lines of dry bulb temperature and wet bulb depression. Each kit
includes a sling psychrometer with wet bulb, wick, rubber band and
a dry bulb thermometer that rotates on a plastic handle.
