• DATA GEM REFRACTOMETER: It is the most important tool for gemstone determination and the most powerful tool for identifying gemstone types. It can measure the refractive index value of gemstones non-destructively, quickly and accurately, and can determine other optical characteristics of gemstones
• DATA GEM REFRACTOMETER STRUCTURE: Data Gem Refractometer is mainly composed of high-sensitivity sensors, intelligent electronic devices, and LCD screens
• WORKING PRINCIPLE: The working principle of the refractometer is based on total internal reflection. The refractive index is a very important optical parameter, and the characteristics of gemstones can be determined based on this parameter
• DATA REFRACTOMETER DOES NOT REQUIRE REFRACTIVE OIL: just put the measuring surface of the sample close to the measuring platform to measure. According to this parameter, it can be determined whether a gemstone is a uniaxial crystal or a biaxial crystal, and whether it is positive or negative phototropism
• SCOPE OF APPLICATION: The refractometer can quickly and accurately identify various single and double gemstones, jade, and jade bracelets. It provides high precision, compactness, portability and easy operation for critical gem identification
