The Optidew Transportable is a dew-point hygrometer that operates on the optical dew-point measurement principle and is easily portable. It is designed for drift-free measurement of the performance of desiccant dehumidifiers in a number of applications. Housed in a specially designed case, the small and lightweight instrument is fully self-contained. The instrument offers a wide measurement range, from the equivalent of less than 0.5% up to 100% relative humidity, and features a high-definition alphanumeric display that shows the measured humidity, dew point, water activity and other hygrometric variables. — Michell Instruments Inc., Rowley, Mass.
