In my defense, I am not an observer and have never encountered this device. Last I probably heard about it was tech school.

a sling psychrometer is used to find the RH in the air. it has two thermometers one has a cotton sock that you pour distilled water on and the other is dry. hints the name dry bulb and wet bulb. you sling it around for a period of time as you sling it the water will evaporate causing the temp to drop the difference between the two is the RH in the air.
