• ★【Essential Gem Identification Instrument】As a cornerstone tool for jewelers, it performs non-destructive refractive index measurements (range: 1.300-3.000) with speed and precision. Critical for verifying gemstone authenticity through optical properties
• ★【High Quality Materials】 The gem refractometer uses hard aluminum alloy to create a work surfaces, which is scratch-resistant and sturdy, providing stable support for precision testing. It is equipped with an ABS engineering plastic power switch and built-in triple insulation protection to effectively block the risk of leakage
• ★【Test Method】No refractive oil is required, just bring the sample's measuring surfaces close to the measuring platform to measure. Based on this parameter, you can determine whether the gem is a uniaxial crystal or a biaxial crystal
• ★【Working Principle】 The working principle of the refractometer is based on total internal reflection. The refractive index is a very important optical parameter, and the characteristics of gemstones can be determined based on this parameter.
• ★【Wide Applications】 Gemstone ldentification Tester Quickly and accurately identify single and double gemstones, moissanite/diamonds/colored gemstones/crystals, designed for measuring the refractive index of gemstones and solid materials. widely used in gem jewelry stores, etc
