By: Frey Scientific Item#: 589686
Frey Scientific Sling Psychrometer is an economical but effective device using the difference in the readings of a wet-bulb and a dry-bulb thermometer to find out the relative humidity. The wet-bulb thermometer is cooled by the evaporation of the water when whirled and shows a lower reading than the dry-bulb thermometer. Comes with a chart for getting relative humidity.

Rated 4 out of 5 by from basic tool at low cost Love this! I did have to glue the thermometer down. Adding the wet sock pulled the probe off the scale and I added a little spot of epoxy to keep it in place. The metal clamp on the glass thermometer has no chance of holding.
