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.
Applications:
Beverages, foods, petroleum, pharmaceutical, alcoholic beverages, etc.
