XFMD-12001A Touchscreen Gold Purity Tester, 1200 g Capacity and 0.001 g/cm³ Resolution (CAT#: STEM-BC-4060-ZJF)

The XFMD-12001A is a touchscreen gold purity tester based on Archimedes water-displacement measurement. It is suitable for jewelry businesses, banks, pawnshops, and precious-metal research laboratories. The instrument determines sample density and supports evaluation of gold and precious-metal purity. It is designed with reference to GB/T 1423 and the listed international density-testing standards. A large LCD provides direct and clear measurement readout. Temperature compensation and solution compensation can be configured for different testing conditions. Upper and lower density limits support rapid acceptance judgment. A buzzer provides audible notification during measurement. RS232C communication supports connection to a computer or printer, while the built-in battery and draft shield improve field usability.
