Sigma Metalytics PRO and Bridge vs XRF

Test through your gold & silver — no drilling, no acids

The Sigma Metalytics PMV PRO probes right through bars up to 45 mm (with External Bridge) and exposes tungsten cores that surface X-ray testers miss.1 2

Surface microns vs full-bar millimetres

Method Depth reached Can it miss tungsten?
Hand-held XRF ≈ 10–20 µm3 Yes — thick plating or a tungsten slug beneath the surface can pass4 5
PMV PRO + External Bridge Up to 45 mm through-bar2 Engineered to flag high-density inserts

“XRF sees µm; PMV PRO sees mm — nowhere for gold-plated tungsten to hide.”

How PMV PRO verifies precious metals

  1. Surface coil measures resistivity of the top layer.
  2. Thru-coil signal passes completely through the bar to an under-sensor, confirming core integrity.6
  3. Algorithm flags any reading outside the green zone for Au / Ag / Pt / Pd.
  4. Optional Refiners Wand & External Bridge let you scan everything from thin sovereigns to 400 oz bricks.

FAQs

Can’t I just scan multiple spots with XRF?

Even multi-spot XRF still reads only ~20 µm deep; a centred tungsten slug stays hidden.4 5

Does the PMV PRO emit radiation?

No. It uses low-power electromagnetic coils — no licence required.6

12.5 mm with onboard sensors; up to 45 mm with the External Bridge.1 2
