The next generation humidity reference standard Optica Series chilled mirror hygrometers offer National Institute of Standards and Technologies (NIST)—traceable humidity, temperature and pressure measurements for the connected generation. Now data is accessible from anywhere, any time, from within a browser over the Internet or from your Intranet.

Optica™ Datasheet I PANAMETRICS 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 measurements call for high precision without long term drift. Optica may be used with four, fully interchangeable chilled mirror sensors to provide a measurement range from -103°F to 185°F (-75°C to 85°C) dew point with 0.36°F (0.2°C) or better accuracy. Inputs for a 100 W RTD and silicon-based piezoresistive pressure transducer ensure precision measurements,...

Optica™ Datasheet Chilled mirror sensors theory of operation These chilled mirror hygrometers are used in standards and metrology labs as well as in industrial applications where precise and repeatable humidity measurement and control is required. 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...

Optica™ Datasheet Digiloop™ control overcomes the limitations of traditional analog PID (Proportional Integral and Derivative) control. Analog temperature control produces oscillations particularly at high or trace humidity levels. It is difficult to apply selftuning or PID constants to analog control loops, which are over damped or under damped. Digiloop utilizes digital sampling and feed-forward control by taking time-based samples when the dew point is within a predetermined proportional band. By recording the oscillations, the digital control effectively predicts the magnitude of change and...
