The Gold Testing Technology That the Perth Mint, Central Banks, and Professional Bullion Dealers Worldwide Rely On — Now Available in the GCC
There is a reason the world’s most serious precious metals professionals — central bank auditors, vault managers, national mints, and professional bullion dealers across Europe, the Americas, and Asia-Pacific — have made Sigma Metalytics the non-negotiable instrument in their verification toolkit.
It works when other methods fail. When a tungsten-filled gold bar passes an XRF surface scan. When a gold-plated coin fools a visual inspection. When a counterfeit silver bar matches the right weight but hides a base metal core. When a professionally sealed assay card contains a fake coin that no one wants to open for testing.
In every one of these scenarios, the Sigma Metalytics Precious Metal Verifier does what no other portable testing instrument can: it uses electromagnetic waves to read the bulk resistivity of the metal all the way through the coin or bar — not just the surface — exposing counterfeits that every other method misses.
From 2025, GCC precious metals businesses in UAE, Saudi Arabia, and Kuwait can access this world-class technology directly through Telos Instruments — the authorized Sigma Metalytics distributor for the region — with local stock, expert guidance, and full after-sales support.
What Is Sigma Metalytics and Why Is It Different?
Sigma Metalytics is an American manufacturer of Precious Metal Verifiers (PMVs) — portable electronic instruments that use a proprietary electromagnetic (eddy current) technology to verify the authenticity and purity of gold, silver, platinum, and palladium bullion coins and bars.
The key word is bulk. While most testing instruments measure the surface of a metal, Sigma Metalytics reads the bulk metal all the way through the coin or bar — meaning there is nowhere for counterfeits to hide.
Thru Readings — The Sigma Advantage
The flagship Sigma Metalytics PMV PRO uses two onboard sensors — one above and one below the sample — to measure resistivity simultaneously at the surface and all the way through the metal. If the surface and the through-reading match, the metal is consistent throughout. If they don’t match, something is hidden inside. This is the only portable field instrument that provides this level of thru-reading verification.
Tests Through Plastic Cases and Slabs — No Removal Needed
One of the most practically valuable features of Sigma Metalytics PMVs is their ability to test through plastic cases, assay cards, coin holders, and cardboard packaging. Gold coins in sealed assay cards, silver coins in certified slabs, and bullion bars in blister packs can all be tested without opening or disturbing the protective packaging. For bullion dealers in the UAE, Saudi Arabia, and Kuwait handling sealed stock, this capability alone saves enormous time and eliminates the risk of damaging packaging during verification.

Frequently Asked Questions
Can the Sigma Metalytics PMV test gold jewelry?
Sigma Metalytics PMVs are specifically designed for gold and silver bullion coins and bars — they are not intended for testing jewelry. For jewelry karat testing, Telos Instruments supplies the GemOro AuRACLE PRO.
What is the difference between the PMV Original, PMV Investor, and PMV PRO?
The PMV Investor is the most compact and portable model for mobile buyers. The PMV Original is the professional counter model for daily bullion verification. The PMV PRO is the flagship professional unit with two onboard sensors, specific gravity testing, and an optional External Bridge for large format bars.
Can Sigma Metalytics detect a tungsten-filled gold bar?
Yes. The PMV reads bulk resistivity all the way through the bar. Tungsten has a different electrical resistivity from gold, producing a reading inconsistent with genuine gold and immediately flagging the item as suspicious.
Can the Sigma Metalytics test gold coins in sealed assay cards without opening them?
Yes. All Sigma Metalytics PMVs can test through plastic cases, assay cards, and cardboard packaging as long as no metal is present in the case itself.
Does Telos Instruments deliver Sigma Metalytics to Saudi Arabia and Kuwait?
Yes. Telos Instruments delivers across the full GCC region — UAE, Saudi Arabia, Kuwait, Qatar, Bahrain, and Oman.
