Polymer capacitance moisture sensors are the most common technology used to measure relative humidity. They are both fast-responding and highly cost-effective.
However, in many industrial applications – such as power generation – using a chilled mirror hygrometer is desirable since they are highly reliable and have virtually no drift. The Michell Optidew 501 is a rugged chilled mirror hygrometer, developed specifically for demanding industrial applications. It uses a new design of chilled mirror sensor that gives it a speed of response that is comparable to a polymer moisture sensor.
Our blog post, How a Michell chilled mirror hygrometer measures relative humidity, explains how to choose the right instrument and what calculations it uses to provide reliable readings of relative humidity in industrial applications.
