Chilled mirror hygrometer Chilled mirror hygrometers are used in standards and metrology labs as well as in industrial applications where precise and repeatable humidity measurement and control are required. The inherent accuracy and long term stability provide many advantages over other types of humidity measurement technologies.

OptiSonde™ Datasheet I PANAMETRICS The OptiSonde chilled mirror hygrometer is a National Institute of Standards and Technology (NIST) traceable humidity transfer standard at an exceptional value. The compact rugged analyzer is 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. An LCD indicates two simultaneous user-configured parameters. OptiSonde provides two user-configured analog (4 to 20 mA) outputs. The display and front panel...

OptiSonde™ Datasheet Chilled mirrors require a nominal flow rate across the mirror to achieve the optimal dew/frost formation and response time. The sensor should either be installed in a duct with moving air or be equipped with a sampling pump. The optimum flow rate is 0.5 to 2.5 SCFH (0.25 to 1.2 L/min). Panametrics provides sampling systems to condition the temperature, regulate the pressure and filter process air before reaching the chilled mirror. Our applications engineers would be pleased to discuss your application in detail and provide a recommendation for the system best suited to your...
