A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from the observed refraction angle using Snell's law. For mixtures, the index of refraction then allows the concentration to be determined using mixing rules such as the Gladstone–Dale relation and Lorentz–Lorenz equation. A refractometer is a handy instrument that can be used to measure samples in a lab, sugars in a food, composition of chemicals and control dilution in a manufacturing in-line .A refractometer is a scientific instrument designed to measure the refractive index of a substance.

measuring instrument for measuring the refractive index of a substancerefractometer - WordReference English dictionary, questions, discussion and forums. All Free. Water has a refractive index of 1.333, meaning that it travels through water 1.333 times more slowly than it would through a vacuum. The higher the refractive index, the slower the passage of light and the more concentrated the liquid. Refractometers work via a combination of a lens and two prisms - one for illumination and one for measuring. .
