Antifreeze Coolant Refractometer 4 in 1 Automotive Antifreeze Meter Car Urea Fluid Tester Glycol Concentration Detector

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