The Michell Instruments Optidew Chilled Mirror Hygrometer is available in bench top and wall mount configurations, and features an intuitive touch screen interface for easy local operation. Using the latest developments in chilled mirror technology, it has a response speed comparable to polymer relative humidity sensors, combined with the reliability of drift-free measurements common to all chilled mirror instruments.

The Optidew offers exceptional accuracy of ±0.15°C for dew point and ±0.1°C for temperature, with repeatability of ±0.05°C and sensitivity of ±0.01°C. The measurement range spans from -40 to 120°C, making it suitable for a wide variety of applications. Two sensor housing materials are available: Polyoxymethylene (acetal) for standard conditions, and PEEK (poly ether ether ketone) for harsh environments. The process connection is M36x1.5.

The instrument's response speed, combined with the fundamental accuracy of chilled mirror technology, makes it an ideal reference instrument for climatic and environmental chambers, as well as for demanding industrial applications requiring precise and reliable humidity measurement.
