• 【Simple And Precise Measurement】Jewelry Authenticity Tester measuring range: refractive index 1.300-3.000.a measurement accuracy of up to 0.001, a measurement error of
• 【Lcd Screen For Clear Reading】Digital refractometer features a large LCD screen, the device ensures excellent readability even in low-light conditions.Powered by a rechargeable 700mAh lithium battery, it supports up to 10,000 measurements per charge
• 【Test Method】No refractive oil is required, just bring the sample's measuring su/rfaces 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
