Refractometer is precision optical instrument that operates on the principle- as the concentration or density of a solution increases, its refractive index changes proportionately. The refractive ...

Refractometers are versatile in their design and use, and are able to provide results as refractive indices, or in other cases, as direct measurements of parameters such as soluble solids, sugar ...
