Psychrometer or wet bulb hygrometer
WebA psychrometer, also known as a hygrometer, is an instrument that measures RH. It consists of two thermometers: a dry-bulb thermometer and a wet-bulb thermometer. The dry-bulb thermometer measures the air temperature, while the wet-bulb thermometer measures the temperature of a wet wick wrapped around the bulb.

To make a wet-bulb thermometer, wrap a piece of white, porous cloth (a hollow white shoelace is ideal) which has been soaked in water around the bulb of one of the thermo-meters and secure it with a rubber band or twine. echocardiography learningWebOct 2, 2024 · Method. Before use, soak the wet bulb wick of your psychrometer in water. Once the wick is wet, hold the handle and whirl the psychrometer in the air. Whirling generates airflow around both the wet and dry bulbs. This action allows water in the saturated wick to evaporate, thereby reducing the temperature of the wet-bulb thermometer. compounds of transition metalsWebCritical Thinking. A sling psychrometer can be used to determine the humidity of the surrounding air because its wet bulb temperature is nearly the same as the adiabatic saturation temperature, and Eq.
