The Model A-525 Sling Psychrometer can be used to measure relative humidity by
measuring the dry bulb and wet bulb temperatures. Wet bulb temperatures are measured
by wetting a wick with distilled water on one of the thermometer legs of the psychrometer.
On the other leg, the dry bulb temperature is measured. An included slide chart eliminates
the need to use of graphs to determine the humidity. Replacement wicks are available as
an accessory. Each sling psychrometer includes psychrometric graphs, psychormetric slide
chart, and a carrying case.
