KERN Digital Refractometer ORF 1RS
Field of application Expert applications

  • The models of the ORF-R series are precise, universal, maintenance-free digital hand refractometers.
  • They are characterised by their easy handling and robustness
  • The ORF-R series is protected against dust and splash water according to the international protection class IP65. You can rinse the refractometer under running water after use.
  • The large and clearly readable TFT colour display with integrated temperature display supports the user in the reliable determination of the measured value.
  • The large selection of models with simple or multiple measuring scales enables use in many areas of application.
  • The optimised instrument software can output measured values in different measuring scales
  • The integrated automatic temperature compensation (ATC) enables simple and fast operation, as no manual conversion of the measurement result is necessary.
  • The factory calibration of the refractometer ensures immediate use and exact measurement of your sample
