Learn how it works, how to use one, and where it’s still practical today. A sling psychrometer requires manual movement (whirling) to create airflow over the thermometers, while. Discover the principles and practical application of the sling psychrometer for precise humidity measurement.

When the sling psychrometer is spun rapidly in the air, the evaporation of the water from the wick causes the wet bulb thermometer to read lower than the dry bulb thermometer.
The psychrometer design exploits these principles to determine relative humidity
If the surrounding air is relatively dry, more moisture will evaporate from the wet. Sling psychrometer consists of a dry bulb thermometer and a wet bulb thermometer for measuring dry bulb temperature of surrounding air and wet bulb. The working principle of a sling psychrometer is based on evaporative cooling When air is dry, more water evaporates from the wet bulb, causing a greater temperature drop.
Sling psychrometers are simple, yet remarkably effective instruments used to measure atmospheric humidity Their operation relies on the principle of evaporative cooling, where the evaporation of water. What is the difference between a sling psychrometer and a stationary psychrometer
