Kern ORA-U Analogue Automotive Refractometer

Features

The KERN ORA refractometers are universal, maintenance-free analogue handheld
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 especially 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 ORA models are equipped with an eyepiece for easy and smooth setting for many different diopter strengths.  The models marked with “ATC” have an automatic temperature compensation which enables accurate measurement at different ambient temperatures (10 °C/30 °C)

The following accessory-parts are included:
- Storage box
- Calibration liquid
- Calibration block (if required)
- Pipette
- Screwdriver
- Cleaning tissue

Further accessories are optionally available
