Description
- The models in the KERN ORA-H 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.
- NEW: Now with engraved serial number
- 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 block
- Contact liquid
- Pipette
- Screwdriver
- Cleaning cloth - Further accessories are available optionally.
- The following model is particularly suitable for measuring the Brix value, the water content in honey and the Baumé degree (°Bé) to determine the relative density of liquids
