GemOro Desktop XRF Gold & Precious Metal Analyzer

Built as a closed-beam, desktop Energy Dispersive XRF spectrometer, the GemOro XRF Assay Lab supports nondestructive analysis for jewelers, appraisers, precious metal buyers, and manufacturers. Suitable for testing gold, platinum, silver, stainless steel (including Rolex 904L), and other precious metals, the analyzer has a silicon drift detector that enables fast surface testing comparable to fire assay without damaging jewelry. It is designed to measure a 3 mm area to a depth of 10 to 20 microns, which exceeds the thickness of typical gold plating. Featuring a 7 inch touchscreen display and a fully enclosed chamber that allows testing with zero radiation exposure, the analyzer offers a scan time of approximately 10 seconds and a lithium-ion rechargeable battery that provides up to six hours of operation.
