Since 1910, General Tools has grown to become the recognized industry leader for specialty hand tools and instruments. This refractometer features a metal body with rubber hand grip blocks and a calibration screen. It also has a cushioned rubber eyepiece and a non-roll stand. The refractometer is mounted in high impact plastic. All water-based solutions can make light bend. The bending of light increases at a rate proportional to the increasing solution concentration. This glycol fluid refractometer is a precise optical instrument that measures the concentration of aqueous solutions by measuring its refractive index. Its characteristics are small and light; it only takes a few drops of solution to use and it is very user friendly.
