The sling psychrometer is a device that uses the wet/dry bulb method where the thermometers are attached to a handle or length of rope and spun around in the air for a few minutes. A psychrometer is a device that consists of two thermometers, one of which includes a dry bulb and one of which includes a bulb that is kept wet to measure wet-bulb temperature.
Amprobe TH-1 Relative Humidity Meter has an easy to read dual display with Data Hold to freeze measurement result on the screen. This relative humidity meter features a precision capacitive RH sensor with twistable protective cap.
Amprobe THWD-3 Sling Psychrometer Wet Bulb uses a precision capacitance sensor to deliver accurate performance with long term stability. This sling psychrometer measures the full range of relative humidity from 0% to 100%.
Amprobe THWD-5 Relative Humidity and Temperature Meter provides easy and quick access to Wet bulb and Dew point values as well as Relative Humidity and Temperature. This relative humidity and temperature meter is equipped with an extended probe for easy target access, a large dual LCD display, and is tripod mountable.
