Refractometer <RA-620/600>
Summary of Test Method
The refractive index is measured using a high-resolution refractometer of automatic digital type with the prism temperature accurately controlled. The instrument principle is based on the critical angle concept.
- Space-saving of "A4 Size"
- Graphic indicator to grasp concentration range
- Easy maintenance with aluminum die casting housing
Applications:
Beverages, foods, petroleum, pharmaceutical, alcoholic beverages, etc.
