Each kind of gem has a typical refractive index due to its chemical composition and crystallization structure. Refractive index is one of most important optical parameter, through the parameters you can judge whether the gem is an anisotropic or isotropic stone. This digital gem refractometer is designed to measure the refractive index of gems with high accuracy 0.007 RI. With the full range from 1.400 to 3.000 RI, it can be used to test almost all kinds of gem. You don't need to apply RI fluid, just simply put your sample on the test platform and read the result on the LCD very quickly and conveniently.A gem refractometer is the primary and most powerful tool in gemstone identification. Therefore, it is widely used in jewelry stores, gem workshops, museums & collections, auctions, laboratories and etcSPECIFICATIONS:Measuring range: 1.400 ~ 3.000 RIAccuracy: 0.007 RIWorking temperature: 10 ~ 28C (50 ~ 82.4F)Power source: 1 x 9V battery (included)Item size: approx. 105 x 60 x 35 mmItem weight: approx. 339g:Wide measuring range: 1.400 ~ 3.000 RIHigh accuracy: 0.007 RINo refractometer oil neededRead results on LCDEasy and simple to use INCLUDE:1 x Digital Gem Refractometer (main unit)2 x Scale Sample1 x Cleaning Cloth1 x 9V battery (included)1 x Instruction ManualCarrying PouchStandard Factory Package  |
