Refractometers & ijkvloeistoffen
Refractometers & calibration fluids for Refractometers. A refractometer is used to determine the refractive index of a liquid or a solid. The refractive index of liquids is used for their identification and for content determinations. The refractive index of a substance is defined as the ratio of the speed of light in vacuum to that in the substance in question. In the event of refraction, Snellius' law applies;
