Refractometer (hand held refractometer, brix refractometer)

A refractometer is an instrument that can measure the concentration of aqueous solution by measuring it's refractive index. All water based solution can make light bend. The bending of light increases at a rate proportional to the increasing solution concentration.The hand-held refractometer is a precise optical instrument. It is characterized by small volume, light weight, graceful shape and easy to operate. Therefore it can be used by all sides
