Panametrics offers single- and multi-stage chilled mirror sensors for moisture measurements from sub-ppm industrial and calibration applications to near-saturation at high-temperature process applications. Driving these sensors are the Optica and OptiSonde display and controllers.
Optica Chilled Mirror Hygrometer - The Optica Chilled Mirror Hygrometer is the best choice for laboratory and calibration applications where precise water vapor control of gas atmospheres is critical. Optica can measure and display on its large color display:
- Relative humidity (% RH)
- Dew/frost point (Td)
- Absolute humidity (m/v)
- Mass mixing ratio (m/m)
- Volume mixing ratio (v/v)
- Wet bulb (Tw)
- Enthalpy (h)
- Water vapor pressure (e)
- Temperature
- Pressure
OptiSonde Chilled Mirror Hygrometer - This hygrometer is the perfect analyzer of choice for laboratory and process measurements. The OptiSonde shares many of the same features as the Optica. Some features include:
- Compact and rugged design for easy installation and durability
- Patented PACER® cycle automatically cleans mirror to ensure measurement integrity
- Built-in data logger provides the ability to record historical data
- Sensor conveniently plugs into wall mount chassis for facility monitoring
- Sensors may be installed to 91 m away for remote monitoring
- Digital (RS-232) interface for data integrity
- Humidity measurements are traceable to the National Institute of Standards and Traceability (NIST)
