What is Concentration Analyzer?

Concentration analyzer is used to measure the concentration of a substance dissolved in a liquid. One of the type of device is refractometers. 

Working Principle

Refractometers emits light into the solution, which is refracted when it crossed the solid-liquid boundary. The refraction angle is compared to the refractive index of the solution. Refractive index is the number that describes how fast light travels in a medium. With a higher refraction index, light travels slower in the medium, which in turns causes the light to be refracted at a greater angle. Solution of different concentration has a different refractive index. Solution with a low concentration has a lower refractive index, producing smaller angle of refraction. So by measuring the angle of refraction, we can measure the concentration of the solution.
