Product Description

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.
