Refractometer - Gemological refractometer is a low cost lightweight measuring instrument used by jewellers and traders of gemstones to measure polished stones over a refractive index range of 1.30 to 1.81 RI. The instrument can also be used to identify whether a particular stone is Isotropic or Anistropic (uniaxial or biaxial). Gemological (Gemstone) Refractometer is your primary and most powerful tool in gemstone identification. As with a typical critical angle refractometer it will measure the Refractive Index of faceted stones. Features: Can identify singly doubly refractive gemstones quickly and accurately. Uniquely designed low battery consumption and portable Approved by strict quality and safety standards for long and trouble-free life Guaranteed, high quality and accurate testing results Specifications: Measuring Range: 1.30 - 1.81 RI Minimum Graduation Value: 0.01 RI Dimension: 30 x 70 x 130mm Weight: 400g Set Includes: 1 x Gem Refractometer 1 x Polarizing Filter 1 x Monochromatic Light Filter 1 x Mini Flashlight 1 x 1.5V AAA Battery 1 x Storage Box 1 x Refractometer 1 x 2ml Vial 1.790 Refractive Index Oil
Digital Refractometer The Digital Gem Refractometer is a nice optical instrument which will give a reading of the Refractive Index of a clean, flat, well-polished, It is an ideal instrument to identify the gem st1s, The importance is that it Can test the gem st1s Without requiring ANY messy, damaging contact oil.
