• The models in the KERN ORA-G 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
