About This Product
Wet and dry bulb hygrometers are used in physics and science classes to find the humidity of the air. Students read both thermometers and note the difference between them, because the wet bulb reads lower as water evaporates from it. Drier air gives a larger difference, and the readings are used with standard tables to find humidity. The instrument is also used to teach evaporation and cooling.
Frequently Asked Questions
Q1. How does the Wet and Dry Hygrometer work?
It has two mercury thermometers, one with a wet bulb and one with a dry bulb. Evaporation from the water on the wet bulb lowers its temperature compared with the dry bulb.
