Gemological refractometer RGM-600 can be used for measuring Refractive index of Gemstone or Ore.
1. The kinds of gem can be precisely determined in accordance with the measured valueof 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.
3. Optional: Customers also can use the 5LCDs as its testing light source!4. Features: 1) RI: 1.30 - 1.81 2) Minimum division: 0.01 3) Accuracy: ±0.01 4) Size: 30 x 70 x 130mm
