  • Page 7: Measuring Principle Of Piox R400

    2 Measuring Principle of PIOX R400 Measuring Principle of PIOX R400 The refractive index n of a solution will be determined by means of transmitted light refractometry. A light beam propagates through the solution and will be refracted at the interface to a prism. The angle of refraction will be measured by a detector.
