Specification Brand : RENJJPBO BulletPoint1 : 【High Quality Materials】: The gem refractometer uses hard aluminum alloy to create a work surfaces, which is scratch-resistant and sturdy, providing stable support for precision testing. It is equipped with an ABS engineering plastic power switch and built-in triple insulation BulletPoint2 : 【Jewelry Tester Identification Tool】: It is the most important tool for gem identification, and can measure the refractive index value of gemstones non-destructively, quickly and accurately. Refractive index test range 1.300-3.000 BulletPoint3 : 【Test Method】No refractive oil is required, just bring the sample's measuring surfaces 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 BulletPoint4 : 【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 BulletPoint5 : 【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 ExternallyAssignedProductIdentifier : 8435814544273 ItemName : RENJJPBO Jewelry Tester Identification Tools,0.001 High Accuracy Jewelry Tester Identification Tools,Gemstone Refractometer with LCD Screens,for Jewelry ItemTypeKeyword : science-lab-refractometers Manufacturer : RENJJPBO MetalType : other PartNumber : gnrer30031 ProductDescription : Specifications: Measuring range: refractive index 1.300-3.000 Measurement error: + -0.005 Measurement accuracy: 0.001 Battery life:10.000 Times Power supply: 700mA Lithium Battery Product Size: 13.5x7.8x2.4cm(5.31x3.1x0.94inch) Net weight: 0.8kg(1.76lbs)
