  • The models in the KERN ORA-B range are universal, maintenance-free analogue manual refractometers
  • The practical and robust design means that it can be used simply, efficiently and on a permanent basis, day in day out
  • The manual effort to convert the value is avoided by the use of several selectable scales and thereby eliminates user error
  • These scales have been specially developed, calculated precisely and checked. Another key feature is the very thin, clear lines
  • The optical system and the prism cover are made from special materials, which enable you to measure with low tolerances
  • All models are fitted with an eyepiece which can be adjusted easily and smoothly to different visual capacities
  • The models which are marked "ATC" have automatic temperature compensation, which makes it possible to obtain precise measurements at different environmental temperatures ( °C - °C)
  • Included in the scope of supply:
    • - Storage box
    • - Calibration solution
