RGM-800

1. The gem refractometer 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.

2. The gemological refractometer is characterized by small volume and less weight. It is easy to carry. It is popular instrument used on jewelry market.
