Description

For determination of dew point and relative humidity. It consists of 9.5’ dry ant wet bulb thermometer mounted on a common back, a water bottle, fan, motor, and 6-volt battery. It is easier to read and provide more consistent results than a conventional sling psychrometer. Components are mounted on a wooden base. The bulb of the lower thermometer is covered with a close fitting tubular muslin wick. When a fan is turned on for a period of 2-3 minutes, water is evaporated from the wick-covered thermometer. The wet bulb and dry bulb thermometers are recorded and the humidity is determined using the chart provided.

Thermometer range is-20 c to 120F or -30 to +50c
