Don’t pay solid prices for plated items

Niton DXL and Niton XL2 gold testers are equipped with proprietary Thermo Scientific AuDIT gold-plating detection technology. Several independent, complementary methods in the AuDIT (Au/gold Detection & Identification Technology) software work in tandem to alert you to the probability that an item is plated, regardless of the gold concentration of the plated surface layer. AuDIT technology works for vermeil (gold-plated silver), as well as gold-plated copper, steel, tungsten and any other non-gold substrate.
