Designed for accurate and quick examination of the

(a) Refractive index. (b) Mean dispersion of liquids, solid and powder.

ND Range:ND 1.300 to ND 1.700 in step of 0.001.Accuracy: 0.002.Sugar(Percentage):0 to 95% in steps of 1 division. Accuracy: 0.5% Temperature: 0-100ºC

The body of the instrument is fixed having a leaning of 60º, correct refractive index and sugar percentage can be read directly in the filed. It consists of a abbe double prism compensaor, telescope mirror limb, graduated sector, reading magnifier and a radial arm which carries a vernier. Abbe's doubleprisms leaves a narrow space(about 0.1 mm.) between the adjoining faces of prisms and compensor consists of the amici prisms which serves for rendering the line of achromatic separation. A thermometer is fitted on the double prisms.....
