Sigma Metalytics PMV PRO – Instant Gold and Silver Verification
At GOLDU we verify the authenticity of investment gold and silver with the professional Sigma Metalytics PMV PRO device – non-destructively, on the spot and even through the original packaging. And we offer you the same certainty: bring your metals in and we will verify them.
What is the Sigma Metalytics PMV PRO
The Sigma Metalytics Precious Metal Verifier PRO is a professional testing device used by precious metals dealers around the world. It works non-destructively – it does not damage the product in any way – and delivers a result within a few seconds.
How the verification works
The device measures the electromagnetic properties of the metal, in particular its resistivity. Every metal and every fineness has a characteristic “electromagnetic signature”. The measured value is compared with the reference range for the given metal and weight – if it matches, the item is very likely genuine metal of the declared fineness.
A major advantage is that the measurement also works through the original packaging. You do not need to take the bar out of its blister or the coin out of its capsule, so the value and integrity of the packaging are preserved.
What we can verify
- investment gold bars and coins (fineness 999.9/1000 Au),
- investment silver (fineness 999/1000 Ag and 999.9/1000 Ag),
- various finenesses and alloys depending on the device settings,
- measurement even through the original blister or plastic capsule.
The technology helps expose common fakes, for example cores of cheaper metals (typically tungsten) hidden under a thin layer of gold, which have different electromagnetic properties.
On-the-spot verification – how it works
- you bring your gold or silver (in its original packaging is fine),
- we place the product on the sensor of the Sigma Metalytics PMV PRO,
- within a few seconds you can see whether the metal matches the declared fineness,
- the whole measurement is non-destructive and damages neither the product nor the packaging.
