Our Digital Gem Refractometer is a nice optical instrument which will give a reading of the refractive index of a clean, flat, well-polished facet to reproducibility of 0.**7RI index units. With covering the full range from 1.*0 to 2.*9RI, It is an ideal instrument to identify the gem stones. The importance is that it can test the gem stones without requiring ANY messy, damaging contact oil. RI Test Range:1.*0 to 2.*9RI Power Input: 9V Battery Work Tempreature: ****8�C
