OSPSHPG Digital Gemstone Refractometer, Jewelry Tester Identification Tools, with Lcd Screens, Refractive Index 1.300-3.000, Measurement Error ±0.005, for Jewelry and Diamond
OSPSHPG
【Gemstone Refractometer】Essential tool for gemstone identification. Measures refractive index non-destructively with high speed and precision. Range: 1.300–3.000. 【High-Quality Build】Equipped with high-sensitivity sensors, smart electronics, and a clear LCD screen for reliable performance. 【Oil-Free Testing】No refractive oil needed—simply place the sample near the measuring platform. Determines if the stone is uniaxial or biaxial. 【Scientific 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 Application】Identifies single/double refractive gems, moissanite, diamonds, and colored stones. Ideal for testing solid materials in labs or jewelry settings.
