  • Digital (RS-232) interface for data integrity

  • Patented PACER® cycle automatically cleans mirror to ensure measurement integrity

  • PanaViewTM software transfers data from the meter to a PC for additional storage and enables data to be viewed graphically

  • Easy to configure using the front panel for simple operation

  • Humidity measurements are traceable to National Institute of Standards and Traceability (NIST)

Applications

  • Environmental test chambers

  • Engine test cells

  • Clean rooms

  • Air conditioning and heat exchange coil testing

  • Metrology labs

The OptiSonde easily records humidity and temperature data from a wide variety of applications. The analyser is equipped with a data logger capable of recording for 100 days at a sample rate of 1 second and is equipped with an internal real-time clock. The saved data is uploaded to a PC using terminal software as ASCII delimited text, enabling it to be opened by Excel® and other spreadsheet programs for data reduction, graphing and statistical analysis.

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 analyser 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 analogue (4 to 20 mA) outputs. The display and front panel keys enable quick and easy configuration.
