Hygrometers measure the moisture content of the air to determine its relativehumidity. Our mechanical hygrometers take advantage of a time-tested method inwhich a synthetic fiber lengthens or shortens based on its absorption ofmoisture from the air. As the humidity changes, the internal coil, made of alayer of the moisture-sensitive fiber bonded to a strip of metal, expands orcontracts to control the pointer. 45% to 70% relative humidity is generallyconsidered to be comfortable.12" Diameter x 2" Deep Accurate Quartz Mechanisms Guaranteed for Life In Stock Ships Fast
