Optica Chilled Mirror Hygrometer

Chilled mirror hygrometer with Ethernet interface and single stage sensor.

The inherent accuracy and long term stability provides many advantages over other types of humidity measurement technologies. Chilled mirrors fundamentally measure the dew or frost point temperature directly by controlling a reflective surface to an equilibrium temperature between dew/frost formation and evaporation, and precisely measuring the temperature of the mirror at this point.  Fundamental dew point measurement is a primary measurement used as a transfer standard for calibrating other humidity instruments and sensors. Chilled mirrors are also the sensors of choice when process and laboratory measure
