- 【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
- 【Jewelry Tester Identification Tool】: It is the most important tool for gem identification, and can measure the refractive index value of gemstones non-destructively, quickly and accurately. Refractive index test range 1.300-3.000
- 【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 Range of Applications】: Quickly and accurately identify single and double gemstones, diamond colored gemstones, designed for measuring the refractive index of gemstones and solid materials
