Scope
This document describes the method of determining the refractive index of liquid chemical products using an Abbe refractometer and a fully automatic refractometer. This document is suitable for the determination of transparent or semi-transparent liquid chemical products with a temperature range of 20℃ to 60℃ and a refractive index range of 1.300 to 1.700.
