Sling Psychrometer

Use this instrument for rapid determinations of the wet and dry bulb temperatures, from which the relative humidity can be derived using tables. Two 9" long matching Fahrenheit spirit-filled thermometers, one with a wick attached to the bulb, are mounted in a metal frame with a folding handle and swivel, enabling it to be whirled rapidly by hand. The results obtained with the psychrometer are more accurate than those obtained with a stationary wet and dry bulb hygrometer. The thermometers have a range of 20–120°F with 1° intervals. Instructions and tables are included.
