All water-based solutions can make light bend, a process known as refraction. The rate at which light bends is in direct proportion to the solution concentration. A refractometer is an instrument that measures the concentration of an aqueous solution by calculating its refractive index. Refractometers are used throughout the food, agriculture, chemical, and manufacturing industries.
DRFH450 Series handheld digital refractometers are lightweight, precise optical instruments that can determine the refractive index in only a few drops of solution. These refractometers are suitable for a wide range of measurement applications, including Brix scale, alcohol, propylene glycol, protein in serum, salinity, Baumé scale, industrial fluids, and specific gravity.
