Description
Digital measurement of refraction index
The KERN ORM refractometers are accurate and universal maintenance free digital handheld refractometers
The large, easy-to-read display with integrated temperature display supports the user to reliably determine the measurement
The integrated automatic temperature compensation (ATC), avoids the manual conversion of the measurement. This allows a quick and
efficient usage of the instrument
Rapid, user-friendly calibration of the refractometer is possible at any time using standard distilled water
The refractometers from the ORM range are protected to international IP65 protection class, against dust and water splashes. After
use, you can rinse the refractometer under running water
Mean value measurements possible
The follwoing accessory-parts are included: – Prism cover lid – Pipette – Storage box – 1 × AAA battery – Screwdriver
