Automatic temperature compensation


  • The models in the KERN ORA-B 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
  • The temperature compensation ("ATC") enables accurate measurement at different ambient temperatures (10 °C to 30 °C)
  • Included with the delivery:
    - Storage box
    - Calibration solution
    - Calibration block if necessary
    - Pipette
    - Screwdriver
    - Cleaning cloth
  • Further accessories are available optionally.
  • This model is particularly suitable for measuring the Brix value. These mean that you can determine the sugar content in foods, primarily in fruit, vegetables, juice and drinks which contain sugar. This refractometer also is ideal for the monitoring of processes in industry (coolant monitoring, oils and fats).
  • The main scope of applications is:
    - Industry: Monitoring of lubricants for process and quality control
    - Food industry: Beverages, fruits and sweets
    - Agriculture: Determination of the degree of ripeness of fruits for quality control in harvesting
    - Restaurants and large-scale catering establishment
