  • The models in the KERN ORA-E range are universal, maintenance-free analogue manual refractometers
  • The handy and robust design allows the easy, efficient and sustainable use in everyday life
  • Manually calculated conversions and errors of the user are avoided by multiple selectable scales.
  • These scales are especailly developed, exactly calculated and checked. They are also characterized by their thin and clear lines.
  • The optical system and the prism cover are made of special material which allows a low-tolerance measuring.
  • All models are fitted with an eyepiece which can be adjusted easily and smoothly to different visual capacities
  • Included with the delivery:
    - Storage box
    - Calibration solution
    - Calibration block if necessary
    - Pipette
    - Screwdriver
    - Cleaning cloth
  • Further accessories are available optionally.
  • Due to a large divided scale this model has a specially large measuring range for the measurement of the refractive index.
  • The main scope of applications is:
    - Universal application, especially when extra large measuring ranges are required
