Easy Ways to Measure Relative Humidity: 8 Steps (with Pictures)

http://pressbooks-dev.oer.hawaii.edu/atmo/chapter/chapter-4-water-vapor/ WebRelative humidity is a term commonly used to describe how much water vapor is in the air as a percent. Saturated air is at 100% relative humidity (RH). Air with a 50% RH and 100°F contains half the water vapor of saturated air at 100% RH and 100°F. Enthalpy describes the heat energy content (BTU/lb dry air) of the air and water vapor mixture.
