The Optica Hygrometer offers precision dew point measurement. Precisely controlled by GE's chilled mirror sensing technology - providing NIST traceable humidity,temperature and pressure measurement anywhere via the worldwide intranet.

The OptiSonde Hygrometer offers precision humidity and temperature measurement. GE's proven chilled mirror sensing technology provides data which is traceable to global metrology and standards laboratories.

The OptiSonde chilled mirror hygrometer is a humidity transfer standard available in benchtop or wall mounted configurations. These compact rugged analyzers are connected to either a single or two-stage chilled mirror sensor and PRTD. Chilled mirrors are the humidity sensors of choice when laboratory and process measurements require high precision without long-term drift.

The Dew-10 Series is a family of low cost, high performance chilled mirror dew point transmitters comprising pipe, duct, and wall mount models. All models provide accurate and reliable dew point measurements over a wide range for energy management and process applications.

In the Dew-10 sensor, a miniature heat pump cools a metallic mirror. When the mirror temperature reaches the dew point of the surrounding air, a thin dew layer condenses on the mirror surface. This condensation is optically detected. A feedback loop keeps the mirror at the exact dew point by continuously controlling the mirror temperature. A precision RTD (Resistance Temperature Detector) is imbedded just beneath the surface of the mirror, allowing the dew point temperature to be accurately measured.
