Gold Testing Machines For Jewellery Retail Stores

Buying and selling gold has become an established market. Since dealers typically have only a few minutes to determine the value of the item offered for sale, unreliable methods such as the touchstone are frequently used. More accurate but also destructive is the time consuming fire assay, X-Ray fluorescence, on the other hand, offers a non destructive , quick and very reliable method for material analysis and coating thickness measurement on jewellery, watches & other precious metal items.
