• Jewelry Tester Identification Tool: The data gemstone refractometer is composed of high-sensitivity sensors and LCD screens.It can measure the refractive index value of gemstones non-destructively, quickly and accurately, and can determine other optical characteristics of gemstones. Measuring range: refractive index 1.300-3.000.a measurement accuracy of up to 0.001, a measurement error of ±0.005.
• Working principle: Based on total internal reflection, it uses the refractive index to determine gemstone characteristics such as uniaxial or biaxial crystals effectively.
• Test method: No refractive oil is required, and it provides reliable results by placing the sample on the platform, ensuring efficient and straightforward operation for frequent use.
• Structure: Featuring high-sensitivity sensors, intelligent electronics, and an LCD screen, it is compact, lightweight, and durable, suitable for various professional environments.
• 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.
