The EMC** refractometer is a microprocessor-driven critical angle refractometer used to measure the refractive index of process liquids. It can be installed directly on the process piping or vessel for measurement and control. The measuring principle of this refractometer is to measure the concentration of a medium using the refraction of light in a medium. When a beam of light reaches the surface of the prism that is in contact with the solution, a part of the reflected light and a part of the refracted light will be produced. When the angle of incidence increases to a certain angle, total reflection will occur. The light emitted by the refractometer light source will hit the prism surface at different angles, resulting in an optical image consisting of light and dark. The angle of incidence corresponding to the dividing line between light and dark in an optical image is the critical angle of total reflection. If the position of the dividing line is determined, the concentration of the solution can also be determined.
The use of EMC** refractometers can reduce production costs and improve product quality. The refractometer is widely used in the measurement of product concentration in various fields such as sugar, fruit juice, beer, and beverages, and can achieve the purpose of optimal control of the production line. In addition, EMC** refractometers have a high measurement accuracy of 005%。
In conclusion, EMC** refractometer is a high-precision, high-reliability measuring instrument that can be widely used in various industrial fields to measure liquid concentration.
