Product Name:
Digital Gem Refrectometer DGR800
Product Explains
The Digital Gem Refractometer is a nice optical instrument which will give a reading of the refractive index of a clean, flat, well-polished facet to reproducibility of 0.007RI index units. With covering the full range from 1.30 to 2.99RI, It is an ideal instrument to identify the gem stones. The importance is that it can test the gem stones without requiring ANY messy, damaging contact oil.
Specification:
RI Test Range:1.30 to 2.99RI
Power Input: 9V Battery
Work Tempreature: 25-28C

gem refractometer / gemological refractometer

Product Name:
RHG600
Product Explains
This model is Gemological refractometer. It can be used for measuring Refractive index of Gemstone or Ore. The index of double refraction can be also measured. Through the parameter you can judge whether a gem is uniaxial or biaxial photopositive or photonegative.
Scale range:1.30-1.81 RI
Minimum Division: 0.01RI

Product Name:
RHG700
Product Explains
The kinds of gem can be precisely determined in accordance with the measured value of refractive index because every kind of gem has its inherent refractive index. Besides, index of double of refraction can be also measured. Through the parameter you can judge whether a gem is uniaxial or biaxial photopositive or photonegative.
The gemological refractometer is characterized by small volume and less weight. It is easy to carry. It is popular instrument used on jewelry market. The model RHG-700 is equipped with a built-in light source. It is more convenient to test!
