MIKON Digital Gem Refractometer Basic Unit (WEEE Reg. No. DE 75181174) for Measuring the Refractive Index of Gemstones

The MIKON Digital Gem Refractometer is a compact and user-friendly instrument designed for the quick determination of the refractive index (RI) of gemstones. Unlike traditional optical refractometers, this device operates without the need for refractive index contact liquid (immersion oil), allowing for clean, convenient and time-saving measurements. The measured refractive index is displayed directly on the LCD screen, providing a fast and reliable aid for identifying a wide range of gemstones. Its compact design makes it suitable for collectors, gemstone dealers, jewellers and gemmology students alike, while the included carrying case ensures safe transport and storage.

The package includes the digital gem refractometer, an instruction manual, a protective carrying case and calibration standards for checking measurement accuracy. The instrument is powered by a 9 V battery (not included) and is designed for use at ambient temperatures of approximately 10 to 28 °C. With a measuring range of RI 1.400 to 2.000, it covers the refractive indices of most gemstones encountered in gemmological work and provides accurate, repeatable measurements when used on properly prepared, flat polished surfaces.
