WebRefractometers measure the extent to which a beam of light bends when it passes through a transparent substance such as a liquid. This can be used to identify the liquid and assess its purity and the concentration of any substances which have been added. How Does a Refractometer Work? WebRefractometers are commonly used to identify a material, determine its purity, or indicate the amount of a dissolved substance that it contains. Lists of standard refractive indexes have been published to help users identify specific compounds or materials. Refractometers also have different scales for specific purposes.
