【EXCELLENT DESIGN】The portable design makes the jewelry refractometer compact and lightweight, weighing only 250 g. And it adopts high-strength aluminum alloy shell, which is scratch-resistant and has a long service life. In addition, it is equipped with an LCD backlit display and ABS insulated switches, with built-in triple insulation protection, ensuring clear and bright viewing comfort while ensuring safe use.Powered by a rechargeable 700mAh lithium battery, it supports up to 10,000 measurements per charge.
【GEM REFRACTOMETER】The digital gemstone refractometer refractive index, as an important optical characteristic parameter of gemstones, is an important basis for distinguishing gemstone types and judging their physical properties. Our gemstone refractometer has a built-in high-precision sensor and performs measurements based on the principle of total internal reflection, can provide scientific and reliable theoretical support for gem identification.
【PRECISE MEASUREMENT】The digital gemstone refractometer as a core tool in the field of jewelry identification, it can measure the refractive index of gemstones non-destructively, quickly and with high precision. Its built-in high-precision sensor covers a measurement range of 1.300-3.000, meeting the identification needs of most common gemstones and providing quantitative data to support identification results. .a measurement accuracy of up to 0.001,a measurement error of ±0.005.
【EASY TO USE】The digital gemstone refractometer no need to use refractive oil, just bring the sample close to the measuring platform to measure. Based on this parameter, you can tell whether the gemstone is uniaxial or biaxial. The process not only simplifies working but also maintains the integrity of delicate gems. In addition, it is equipped with two calibration blocks of 1.487 and 1.806, which need to be calibrated before measurement to ensure the accuracy of the measurement results.
【WIDE APPLICATION】Designed for measuring the refractive index of gemstones and various solid materials, it can quickly and accurately identify single crystal gemstones, twin crystal gemstones, diamonds and various colored gemstones. It is widely used in jewelry appraisal institutions, gem processing factories, collectors and other scenarios.
