When many people hear “refractometer”, they think about the device that measures sugar concentration. Most devices that measure sugar concentration are of this same configuration, wherein light is shined through a prism onto the test sample, and the angle of refracted light changes for each sample. By measuring the refraction (refraction rate) of light, the refractometer can be used as a measuring device various concentration.
