Optical refractometer AB1

Abbelaboratorybenchtop

The ABBE refractometer is intended for measuring the refractive index ND and the average dispersion nF-nC of trasparent or translucent liquid, or solid substance (of whic mainly intended for measuring trasparent liquid), In case of the instrument being connected with a thermostat, i twill be able to measure the refractive index ND at a temperature betwenn 0° and 70° C. Both the refractive index and average dispersion are the important optical constans, througth which we can understand the optical performance, purity, concentration, as well as dispersion of a substance. In this instrument based on the formula provided by the International Commission of Uniform Method of Sugar Analysis (ICUMSA) in 1974, the refractive index is converted into the mass fraction (BRIX) of cane sugar solution, with a range of conversion from 0 to 95%. Therefore, this instruments has found an increasingly wide utilization in the fields as petroleum, oil , pharmaceutical, paint, food, chemical and sugar refining industries, as well as in geological prospecting enterprise, colleges, universities and scientific research institutions.
