(Digital Refractometer, Hand-held Refractometer, Hand Held Refractometer, Illumination Hand Held Refractometer, Abbe Refractometer, Bench-top Refractometer, Gem Refractometer, Gemological Refractometer)
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! Specification: Range: 1.30-1.81RI Minimum Division: 0.01 |
