Analogue refractometer Kern ORA-AL, Volume percent. Application beer and alcohol production.

• The models in the KERN ORA-AL 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
• All models are fitted with an eyepiece which can be adjusted easily and smoothly to different visual capacities:
  • Storage box
  • Calibration solution
  • if necessary, calibration block
  • Pipette
  • Screwdriver
  • Cleaning cloth
  • Further accessories are available as options

Area of application: Beer/Alcohol

The following models are particularly suitable for determining the sugar content of the original wort in its unfermented state. The value can be read straightaway, without having to be converted, using the SG Wort and Degrees Plato scales. In addition, the percent by volume and percent by mass scales can be used to determine the alcohol content of clear spirits

Main areas of application

• Alcohol production
• Beer brewers
