Optica Chilled Mirror Hygrometers

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 Optica Hygrometer measures dew point temperature by regulating the temperature of a polished metal mirror by the use of optical feedback such that a constant mass of dew or frost is maintained. The temperature of the mirror is measured with a precise PRTD and is by definition equal to the dew or frost point.

OptiSonde Chilled Mirror Hygrometer

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.
