Sigma Metalytics PMV Original vs Investor vs PRO: Which One Should You Buy?

By Telos Instruments Trading LLC · Exclusive Sigma Metalytics Distributor (UAE) · Deira, Dubai, UAE

Quick answer: The PMV Original offers resistivity-only testing and is the entry point into Sigma Metalytics’ non-destructive coin and bar verification technology. The PMV PRO adds density testing, an adjustable sensor arm, a full keypad, and an optional External Bridge for scalable, high-volume dealer use. The PMV Investor shares the PRO’s resistivity-and-density capability in a configuration built for private investors and collectors managing significant personal holdings. All three are completely non-destructive, can test through sealed packaging, and are designed exclusively for coins and bars — not jewelry.

Telos Instruments Trading LLC is the exclusive distributor of Sigma Metalytics in the UAE, supplying the full PMV Original, PMV PRO, and PMV Investor range to bullion dealers, coin shops, refineries, banks, and private investors across the UAE and wider GCC, with local demos and after-sales support.

Understanding the PMV Technology Before Comparing Models

All three Sigma Metalytics PMV devices share the same foundational technology: resistivity testing. A sensor generates a small electromagnetic field and measures how a sample distorts that field as it passes through it. Genuine precious metal alloys have known, consistent resistivity signatures, so the device compares your sample’s reading against the expected result for the alloy selected from its built-in database — a match means the sample passes, a mismatch flags something worth investigating.

The PMV PRO and PMV Investor add a second, independent layer: density testing. Sensors above and below the sample measure thickness, the user enters the item’s weight, and the device calculates the dimensions a genuine sample of that alloy and density should have. This second check is particularly valuable against sophisticated fraud like tungsten-core bars, where the core material’s density is nearly identical to gold’s — close enough to pass a resistivity or weight check alone in some cases, but caught by the combination of both tests together.

Across all three models: no chemicals, no ongoing calibration maintenance, and the ability to test directly through plastic cases, coin flips, holders, and sealed assay packaging (provided there’s no metal in the packaging) — meaning graded or slabbed coins and bars can be verified without breaking their seal.

PMV Original

The PMV Original is the foundation of the Sigma Metalytics lineup and the most accessible entry point into the technology.

What it includes: The PMV Original unit, all three included wand attachments (Small, Large, and Bullion wands, covering a wide range of coin and bar sizes), a charger, carrying case, manual, and a 2-year warranty.

What it does: Resistivity testing only — no onboard density testing, adjustable sensor arm, or keypad.

Who it’s for: Coin shops, smaller dealers, and individual collectors who want reliable, non-destructive resistivity-based authentication without the added hardware and complexity of the higher-tier models. For many collectors and smaller operations, resistivity testing alone — paired with good judgment on provenance and visual inspection — is sufficient day-to-day protection.

PMV PRO

The PMV PRO is built for active dealers and higher-throughput verification work.

What it adds over the Original: Onboard density testing alongside resistivity testing, an adjustable sensor arm capable of testing samples up to 10mm thick, and a full keypad for fast entry of sample alloys and weights — speeding up verification when testing many items in a session.

Scalability: The PMV PRO supports an optional External Bridge accessory for expanded verification capability. Each External Bridge is factory-calibrated and serial-matched to its specific parent PRO unit, allowing dealers to scale their verification setup as volume grows.

Who it’s for: Bullion dealers, coin shops with regular buy-back and resale volume, and refineries that want both resistivity and density confirmation on every item that crosses the counter, with room to expand their setup over time.

PMV Investor

The PMV Investor shares the PMV PRO’s core technical capability — resistivity testing, density testing, an adjustable sensor arm (up to 10mm sample thickness), and a full keypad — but is configured and marketed specifically for private investors and serious collectors.

What it’s built for: Someone managing a significant personal gold or silver holding — rather than running a commercial dealing operation — who wants the same dealer-grade verification confidence as a professional bullion business, applied to their own collection or investment portfolio.

Who it’s for: Private investors with meaningful bullion holdings, serious coin and bar collectors, and anyone who wants to verify purchases or periodically audit a personal stockpile without needing the commercial-scale accessories (like the External Bridge) built for dealer throughput.

Side-by-Side Comparison

How to Choose Between the Three

1. If you’re a smaller coin shop or a collector just starting out — the PMV Original gives you reliable, non-destructive resistivity verification at the lowest barrier to entry into the technology.
2. If you run a busy bullion counter or refinery — the PMV PRO’s combination of resistivity and density testing, plus the option to add an External Bridge as volume grows, makes it the strongest fit for commercial throughput.
3. If you’re a private investor or collector with a substantial personal holding — the PMV Investor gives you the same resistivity-and-density verification confidence as a professional dealer, scaled to personal rather than commercial use.
4. If you handle both coins/bars and jewelry — remember none of the PMV models test jewelry; you’ll need a separate tool (such as an XRF analyzer or pen-probe tester) for that category, alongside whichever PMV model fits your bar and coin volume.

Telos Instruments Trading LLC: The Exclusive Sigma Metalytics Distributor in the UAE

Telos Instruments Trading LLC, based in Al Uthman Building, Deira, Dubai, is the exclusive distributor of Sigma Metalytics in the United Arab Emirates. This means the full PMV Original, PMV PRO, and PMV Investor range — along with genuine accessories, wands, and factory-calibrated External Bridge units — is available locally through Telos Instruments, rather than requiring customers in the UAE to import directly from Sigma Metalytics’ US operations.

Buying through the exclusive local distributor means:

• Live demonstrations on your own coins and bars before you commit to a model
• No international shipping delays or customs uncertainty on your order
• Local after-sales support and guidance, with a regional point of contact for questions or servicing
• Confidence in product authenticity and warranty support, sourced through the official UAE distribution channel rather than a secondary reseller

For bullion dealers, coin shops, and private investors across the UAE and the wider GCC, working with Telos Instruments as the exclusive Sigma Metalytics distributor removes the friction, cost, and uncertainty of ordering specialized verification equipment from overseas.

Frequently Asked Questions

Final Thoughts

The right Sigma Metalytics PMV model comes down to volume and purpose: the PMV Original for reliable entry-level resistivity verification, the PMV PRO for active dealers and refineries who need both resistivity and density testing with room to scale, and the PMV Investor for private investors and collectors who want dealer-grade protection for a personal holding. All three share the same core promise — fast, chemical-free, non-destructive verification, even through sealed packaging.

As the exclusive distributor of Sigma Metalytics in the UAE, Telos Instruments Trading LLC can help you compare the three models against your own coins and bars before you buy.
