Measure relative humidity. Two thermometers are mounted on a heavy-duty plastic wall-mounting panel. One thermometer remains dry; the second thermometer has a cotton wick attached to its bulb, which dips into a plastic cistern filled with water. The relative humidity is determined by comparing the temperature readings of each thermometer against the tables found in the relative humidity chart provided.
