An Abbe Refractometer is used to measure the refractive index and mean dispersion values of transparent liquids or solids. This refractometer is a highly used tool within a wide range of industries.A) A designed and quick examination of theB) mean dispersion of liquids, solids, and powderThe body of the instrument is fixed having a learning of 600, correct refractive index and sugar percentage can be read directly in the need. It consists of a double prism compensator, telescope mirror limp, graduated sector, reading magnifier, and a radial arm that carries a vernier, Abbes double prism leaves a compensator consisting of the amici prism which serves for rendering the line of achromatic separation. Thermometers are fitted on the double prism.
