Designed for accurate and quick examination of the
(a) Refractive index (b) Mean dispersion of liquids, solids and powder.
ND Range:ND 1.300 to ND 1.700 in step of 0.001
Sugar(Percentage):0 to 95% in steps of 1 division.
The body of ABBE Refractometer instrument is fixed having a leaning of 600, correct refractive index and sugar percentage can be read directly in the field.ABBE Refractometer consist of a abbe double prism compensaor, telescope mirror limb, graduated sector, reading magnifier and a radial arm which carries a vernier.Abbe's double prisms leaves a narrow space(about 0.1mm.) between the adjoining faces of prism and compensator consists of the amici prisms which serves for rendering the line of achromatic separation.A thermometer is fitted on the double prism.
