Analogue refractometer ORA-U

• The models in the KERN ORA-U 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
  • - Pipette
  • - Screwdriver
  • - Cleaning cloth
• Further accessories are available as options

The following models are particularly suitable for measuring and determining AdBlue, glycol concentration (ethylene: EG and propylene: PG), of battery fluid (BF), urea and measuring the freezing point of screen wash (CW). Furthermore, these models are suitable for measuring temperature-exchange systems. 

Main areas of application: 

• Motor vehicle industry
• Chemical industry
• Solar industry (checking frost protection)
• Geothermal power (measuring brine concentration with geothermal energy)
• Forestry management
