• 1. Jewelry Tester Identification Tool: The Professional Gem Refractometer is equipped with high-sensitivity sensors and an LCD display, allowing for quick and accurate measurement of the refractive index values of gemstones non-destructively. It features a measuring range of 1.300 to 3.000 with an impressive accuracy of 0.001 and a measurement error of ±0.005.
• 2. Test Method: Utilizing the Professional Gem Refractometer does not require any refractive oils. Simply bring the sample's measuring surfaces close to the platform to obtain results. This tool helps identify whether the gem is a uniaxial or biaxial crystal, enhancing your gemstone identification process.
• 3. High Quality Materials: Constructed from durable hard aluminum alloy, the Professional Gem Refractometer provides a scratch-resistant work surface that ensures stability during precision testing. Its ABS engineering plastic power switch and built-in triple insulation protection safeguard against potential leakage risks.
• 4. Wide Applications: The Professional Gem Refractometer is designed for versatile usage in identifying both single and double gemstones, including moissanite, diamonds, colored gemstones, and crystals. This makes it an essential tool for jewelry stores and gemologists alike.
• 5. Working Principle: The Professional Gem Refractometer operates on the principle of total internal reflection, which is crucial for determining the refractive index, a vital optical parameter. This powerful tool is indispensable for accurately measuring gemstones and identifying different gem types effectively.
