![]() Methodīefore use, soak the wet bulb wick of your psychrometer in water. In a nutshell, a psychrometer determines humidity by correlating temperature movement. ![]() If the air is more humid, evaporation will be less, and the fall in temperature will be lower. If the surrounding air is relatively dry, more moisture will evaporate from the wet bulb, and the drop in temperature will be higher. The psychrometer design exploits these principles to determine relative humidity. In saying this, air only holds a limited amount of water, after which it becomes saturated, and at this point, water will not evaporate as quickly. When water on a surface evaporates, it extracts heat, which in turn, cools a surface down significantly. This thermometer is called the ‘Wet-Bulb Thermometer.’ The other thermometer remains exposed to air and is known as the ‘Dry-Bulb Thermometer.’ On the end of the thermometer housing, is a pivoting handle you use to rotate the psychrometer.įigure 1 Labelled Sling Psychrometer Working Principle You must soak this wick in water before use. A wick covers the bulb of one of the thermometers. Psychrometer DesignĪlthough each make and model will vary slightly, the fundamental sling psychrometer design consists of two thermometers contained within a plastic housing. Suitable applications include educational purposes, laboratory use, and for measuring the humidity of storage areas. You should consider Psychrometers for environmental monitoring and capturing field measurements if portability and low maintenance are your critical considerations. Psychrometers are excellent tools because they: Psychrometers are battery-free hygrometers that offer a straightforward way of obtaining humidity measurements. Hygrometers measure the relative humidity of an environment. Yet, this popular piece of scientific equipment that measures humidity is still incredibly useful and widely used today. Psychrometers are by no means a new invention and have barely changed in recent decades.
