ORIDLECTAL Gem Identification Tools with Refractive Index 1.300-3.000, High Accuracy: 0.001 and Low Measurement Error: ±0.005, Professional Gemstone Tester for All Jewels

• ◆【Precise and reliable】:Our Gemstone Refractometer employ high-refractive-index optical glass prisms and precision calibration technology,it provides accurate refractive index measurements ranging from 1.300 to 3.000, with an exceptional accuracy of ±0.005 and resolution of 0.001. Ensure accurate measurements every time, providing the most reliable data support for your identification conclusions. It provides objective, quantifiable data.
• ◆【Highly Efficient】:The Gemstone Tester ensures excellent readability even in low-light conditions as it featuring a large LCD screen with backlight illumination, a high-sensitivity sensor, and intelligent electronics.Powered by a rechargeable 700mAh lithium battery, it supports up to 10,000 measurements per charge, making it suitable for lab use, field gemology trips, and jewelry store applications.
• ◆【Easy to Use】:Stable readings can be obtained with simple operation. Unlike traditional methods, this gem Identification Instrument requires no refractive oil.First, press the TEST button once to turn on the machine. Second, press and hold the TEST button for 5 seconds to begin calibration. Then,please use tweezers to pick up the calibration blocks one by one for instrument calibration. When the reading shows 1.000, the instrument calibration is complete and it is ready for normal use. Making identification work easy and efficient, also maintains the integrity of delicate gems.Even beginners can quickly master it.
• ◆【Sturdy and durable】:The gem refractometer uses hard aluminum alloy to create a work plate, which is scratch-resistant and sturdy, providing stable support for precision testing. It is equipped with an ABS engineering plastic power switch and built-in triple insulation protection to effectively block the risk of leakage
• ◆【WIDE COMPATIBILITY】:Refractive index testing is a crucial step in gemstone identification. Our Gem Tester provides a non-destructive, rapid, and accurate measurement of a gemstone's refractive index, helping to determine its type, moissanite, diamond, colored gems, natural or synthetic stones, minerals, and other solid materials. A must-have for gemologists and serious collectors.
