As a widely used physical asset investment, gold's pawn recycling is a high return, high yield, and high-risk industry. In actual investment transactions, the phenomenon of insufficient quality or adulteration of gold and silver jewelry (such as tungsten and rhenium doping and gold wrapping) often occurs. To ensure the quality of recycled gold and avoid risks, choosing traditional time-consuming and destructive testing or rushing to third-party testing at high costs every day can no longer meet customer needs and cost control.

The company's precious metal detector can quickly, accurately, and non-destructive identify the specific composition and content of gold, helping customers avoid risks and achieve controllable risks.
