The refractometer is an optical instrument that analyzes the behavior of light when it passes from one medium to another. It is therefore very important that both the prism and the prism cap are clean, dry and without scratches. This refractometer with lighting works like virtu

The refractive index of the examined liquid determines the angle at which the measuring prism light hits the lens. The refractive angle determines which areas of the measuring scale are illuminated. At the boundary between light and darkness, the value of the tested liquid can be

You can check the accuracy of the Brix refractometer with lighting using distilled water and a special calibration liquid. If when using distilled water you do not read a value of 0 % Brix, respectively the corresponding value of the calibration liquid,

The Brix refractometer scale with lighting has been designed to work at a temperature of 20 oC. It is necessary to take into account that the refractive index of a material depends on the temperature. For this reason it is important to take into account that both the device and the sample must have
