Feature

●High quality: The gem refractometer is the most important tool for gem determination and the most powerful tool for identifying gem species
●Stainless steel countertop: the use of metal and stainless steel, scratch-resistant and durable, to prevent corrosion
●Power supply device: 3 button batteries (not included) built-in LED lights; professional optical design and built-in narrow-wavelength quasi-monochromatic LED light source, making the shadow boundary super flat and clear; black background high-contrast ruler makes the interface clearer and clearer
●High precision: The refractometer has high precision and is easy to operate. High cost performance, simple and error-free operation, it is a stable diamond measuring instrument.
●Small and portable: The gem refractometer is specially used to measure the refractive index of gems and solid materials. The size is about 133*32*61mm. It is characterized by its compactness and lightness. It is very popular in the jewelry industry. Many people consider it to be the most important of all gemstone testing instruments.


Description

The gem refractometer is the most important tool for gem determination and the most powerful tool for identifying gem species. It can measure the refractive index of gems non-destructively, quickly and accurately, and can determine other light characteristics of gems.

This gemstone tester uses high refractive index lead glass as the test prism; measuring range: 1.30-1.81, accuracy: ±0.002, power supply device; built-in LED light with three button batteries; professional optical design and built-in narrow wavelength quasi-single The color LED light source makes the shadow boundary super straight and clear; the black background high-contrast ruler makes the interface clearer and clearer
