Which Sigma Metalytics PMV Should You Buy in the UAE?

By Telos Instruments Trading LLC · Exclusive Sigma Metalytics Distributor (UAE & GCC) · Al Uthman Building, Deira, Dubai, UAE

Quick answer: Buy the PMV Original if you want straightforward, non-destructive resistivity testing for coins and bars you hold as a personal investment. Buy the PMV Investor if you hold a larger personal collection and want an added density check, an adjustable sensor arm, and a full keypad. Buy the PMV PRO if you use the device in a business, such as a bullion dealership, coin shop, or refinery, and need resistivity plus density testing with room to scale through the optional External Bridge. None of the three is designed for jewellery.

Telos Instruments is the exclusive distributor of Sigma Metalytics in the UAE and GCC, supplying the full PMV range with local demonstrations and after-sales support from Al Uthman Building, Deira, Dubai.

First, What Every PMV Has in Common

Before comparing models, it helps to know what all three Sigma Metalytics PMV devices share.

• Patented resistivity testing. The sensor generates a small electromagnetic field and measures how the sample affects it. Genuine precious metal alloys have known resistivity profiles, so the device compares your coin or bar against the profile for the alloy you select from its built-in database.
• Non-destructive. No chemicals, no drilling, no cutting, no marks.
• Tests through sealed packaging. PMV devices can test through plastic cases, coin flips, holders, and sealed assay packaging, as long as there is no metal in the packaging. Graded and slabbed items can be checked without breaking their seal.
• No ongoing calibration maintenance in normal use.
• 2-year warranty on each model.
• Coins and bars only. Sigma Metalytics does not design or recommend the PMV for testing jewellery. For jewellery, use an XRF analyzer such as the Terra Scientific Aurora 900 or Pi900E, also available from Telos Instruments.

The differences between models come down to density testing, convenience features, and scalability.

PMV Original: Best for Personal Investors Starting Out

The PMV Original is the entry point to Sigma Metalytics technology.

• Testing method: resistivity
• Included: Small, Large, and Bullion wand attachments for different coin and bar sizes, plus charger, carrying case, and manual
• Warranty: 2 years

Choose it if:

• You buy gold or silver coins and bars as a personal investment and want a reliable, non-destructive check before and after purchases
• You want the simplest, most accessible way into PMV verification
• You mainly buy standard coins and bars, and a resistivity check meets your needs

Think twice if: you hold large or high-value bars and want a second, independent density check, in which case the Investor is the better fit.

PMV Investor: Best for Serious Personal Holdings

The PMV Investor is configured for individual investors and collectors with more at stake.

• Testing methods: resistivity and density
• Adjustable sensor arm: tests samples up to 10mm thick
• Full keypad: quick entry of alloy and weight
• Warranty: 2 years

Why density matters: the density test works by measuring the sample’s thickness while you enter its weight, then checking whether the dimensions are consistent with the selected alloy’s density. Combined with resistivity, it provides a second, independent line of defence. That is particularly relevant to tungsten-core counterfeits, because tungsten’s density is almost identical to gold’s, which makes weight-based checks alone unreliable.

Choose it if:

• You hold a substantial collection of bars or coins and want more than a resistivity-only check
• You want to verify new purchases carefully and audit existing holdings
• You value a keypad and adjustable arm for faster, more flexible testing

PMV PRO: Best for Business Use

The PMV PRO is the business-use model in the range.

• Testing methods: resistivity and density
• Adjustable sensor arm: up to 10mm sample thickness
• Full keypad
• Optional External Bridge: each Bridge is factory-calibrated and serial-matched to its parent PRO unit, giving dealers a way to scale verification capacity as volume grows
• Warranty: 2 years

Choose it if:

• You run a bullion dealership or coin shop and verify items at purchase and resale
• You operate a refinery or vault and need to check incoming bars and coins
• You are a jewellery shop that also buys and sells bullion (and keep an XRF analyzer for the jewellery itself)
• You want resistivity and density confirmation on every item, with a path to expand

Side-by-Side Comparison

A Simple Decision Guide

1. Do you need it for jewellery? The PMV is not the right tool. Use an XRF analyzer (Aurora 900 benchtop or Pi900E handheld).
2. Is it for a business? Choose the PMV PRO.
3. Is it personal, and do you want density testing too? Choose the PMV Investor.
4. Is it personal, and is a resistivity check enough for you? Choose the PMV Original.
5. Do you handle both jewellery and bullion? Pair an XRF analyzer with a PMV (the PRO if it is a business).

Why Buy Through Telos Instruments, the Exclusive Distributor in the UAE and GCC

Telos Instruments is the exclusive distributor of Sigma Metalytics in the UAE and GCC. For buyers, that means:

• A single local source: the full PMV Original, PMV Investor, and PMV PRO range, plus accessories, available in the UAE rather than imported on your own
• Demonstrations before you buy: see a PMV test your own coins or bars and compare models side by side
• Local support: guidance on correct use, and a regional contact for questions or servicing

Frequently Asked Questions

Final Thoughts

Choosing a PMV is mostly a question of how you’ll use it. The PMV Original gives personal investors a dependable entry point. The PMV Investor adds density testing and convenience for larger holdings. The PMV PRO is built for business use and scales through the External Bridge. All three are non-destructive, can test through sealed non-metal packaging, and are for coins and bars, not jewellery. With Telos Instruments as the exclusive Sigma Metalytics distributor in the UAE and GCC, you can compare the models in person and buy with local support.
