Refractometry is the analytical method of measuring substances' refractive index (one of their fundamental physical properties) in order to, for instance, assess their composition or purity.

Refractometry is the measurement of a substance’s refractive index (Caldas, 2015; Anderson, 1920), and is often used to characterize glasses, liquid foods, and other transparent materials.

Refractometers are widely used analytical devices in quality assurance. From light to dark, from alkaline to acidic, from low to high viscosity – our refractometers can measure almost all samples.

Refractometry is a quantitative, non-destructive measuring technique based on optical principles that are evident in nature: For example, when light passes through water, the light beam is …
