Have you tested gold plated bars with DUX?
Before launching DUX we have tested the system on a gold plated tungsten bar to validate our testing processes. We are very pleased with the results as gold plated tungsten bars have failed all three DUX tests with the ultrasound test being the most obvious.
During the months preceding the launch of DUX Bullion Testing, we were able to demonstrate the process on genuine and gold plated tungsten test bars to several mints and major bullion dealers as well as an LBMA Referee and have consistently received praise and approval of these processes.
