Gem Refractometer Digital Handheld Gem jewelry  Refractometer Range 1.30-1.81

Features

Wide Measuring range: 1.30 ~ 1.81 RI

High Accuracy: 0.01 RI

Built-in LED illumination

Brief Description

Each gem has a typical refractive index due to its chemical composition and crystallization structure. The gem refractometer can be used to observe the optical properties and the structure of a gemstone. Through the parameters you can judge whether the gem is an anisotropic or isotropic stone. The stone needs a flat and polished facet. FULL SCALE Contact Liquid (RI Fluid) is also needed when testing.

This Gem refractometer is a compact refractometer with built-in LED illumination for the determination of the refractive index (RI), quality and categories of gemstones.
