An instrument for measuring a refractive index, which is related to the amount by which the angle of a light wave is changed when passing through the boundary between two media. The amount of refraction is a convenient way to measure solute concentration of a solution and is widely used in viticultural and winemaking to follow the ripeness of grapes and changes during vinification.
