Digital Gemstone Refractometer, Jewelry Tester Identification Tools with Display, 0.001 High Accuracy, Measurement Error ±0.005, for Jewelry and Diamonds

Specification Name: Gem Refractometer Measuring range: refractive index 1.300-3.000 Measurement error: +-0.005 Measurement accuracy: 0.001 Appearance size: 13.5X7.8X2.4CM Package includes: 1*Digital Gem Refractometer

• TEST METHOD: No refraction oil is required, just place the measuring of the sample close to the measuring platform to measure. Based on this parameter, you can determine whether the gemstone is a uniaxial or biaxial crystal.
• WIDE RANGE OF USES: Quickly and accurately identify single and double gemstones, moissanite/diamonds/colored gemstones, specially designed for measuring the refractive index of gemstones and solid materials.
• GEM REFRACTOMETER: 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.
• WORKING PRINCIPLE: The working principle of the refractometer is based on total internal reflection. Refractive index is a very important optical parameter based on which the properties of gemstones can be judged.
• QUALITY: The data gemstone refractometer is composed of high-sensitivity sensors, intelligent electronic devices, and LCD screens. The most important tool for gemstone measurement is also the most powerful tool for identifying gem types.
