Testing methods you should avoid

Many conventional methods are inaccurate, expensive, or damage the product:

  • Acid tests damage the surface
  • Drill tests destroy the bar
  • Ultrasound often only detects surface-level deviations
  • X-ray methods are costly

In contrast, the GVS Bullion Tester works non-destructively, quickly, and reliably.

The GVS Bullion Tester contains a strong magnet.

  • Keep distance from other electronic devices
  • Maintain at least one meter distance from other metal objects
