Enjoy the simplicity of refractive index measurement without maintenance or adjustments

  • Soldered optics: no serviceable sealing with full CIP/SIP capability
  • Full range sugar scale instrument 0 to 100%
  • Accomplishes hygiene requirement according to the European Hygienic Engineering & Design Group
  • Integrated display and evaluation unit with standard industrial interfaces
  • Fulfills the NAMUR recommendation NE 107 (self-monitoring and diagnosis)

Key Features


  • Industry-leading soldered optics need no liquid seals and ensure maintenance-free operation
  • You benefit from «install and forget» simplicity and years of continuous performance

Never requires adjustment

  • Proprietary calibration and adjustment procedure
  • Sensor operates with its factory settings for its entire service

Enjoy high accuracy

  • Efficiently handles from 0 to 100 weight concentrations and provides refractive index and concentration results comparable to those of laboratory refractometers
  • Once CIP/SIP routines are completed, the sensor reactivates in just minutes to minimize downtime

Ideal for pharmaceutical, food and beverage applications

  • EHEDG-certified
  • Designed ot meet the ASME Bioprocessing Equipment Standard
  • CIP and SIP up to 145 °C

Intelligent measurement

  • Intuitive touchscreen makes it easy to set
  • Meets NAMUR NE107 standards and provides user-friendly diagnostics based on standard status categories

Various communication possibilities

  • Full connectivity by fieldbus communication (PROFIBUS DP, Modbus TCP, PROFINET, DeviceNet or EtherNet/IP protocols) or
  • Classic analog outputs (4-20mA) and digital-IOs available
