RGM-900

Gemological refractometer RGM900 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.

It is characterized by small volume and less weight. It is easy to carry. It is popular instrument used on jewelry market. This RGM-900 is a professional model for issuing the certificate for gemstones. It is most popular used om labs and jewellery insitutes.
