Can Sigma Metalytics Test Gold Through Packaging?
By Telos Instruments Trading LLC · Exclusive Sigma Metalytics Distributor (UAE & GCC) · Al Uthman Building, Deira, Dubai, UAE
Quick answer: Yes. Sigma Metalytics PMV devices can test gold and silver coins and bars through plastic cases, coin flips, holders, and sealed assay packaging, as long as there is no metal in the packaging. That lets you verify graded, slabbed, or sealed items without breaking the seal. They cannot test through metal packaging, and they are designed for coins and bars only, not jewellery.
Telos Instruments is the exclusive distributor of Sigma Metalytics in the UAE and GCC, supplying the full PMV Original, PMV Investor, and PMV PRO range with demonstrations and local support from Al Uthman Building, Deira, Dubai.

Why Testing Through Packaging Matters
For many buyers of physical gold, the packaging is part of the value.
- Graded and slabbed coins are sold in sealed holders precisely so that their authenticity and condition are certified. Breaking the seal to test them can destroy that certification and reduce resale value.
- Bars in sealed assay packaging carry the refiner’s authentication details. Opening the pack can compromise the very proof that makes the bar easy to sell.
- Investors and dealers want to verify purchases at the point of sale without asking a seller to open sealed items, and want to audit stored holdings without disturbing them.
A verification method that works only on bare metal forces you to choose between certainty and condition. Testing through packaging removes that trade-off.
How the Sigma Metalytics PMV Works
The PMV (Precious Metal Verifier) range is built on patented testing technology.
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 item against the profile for the alloy you select from its built-in database. A match passes; a mismatch is a reason to investigate.
Density Testing (Investor & PRO)
Sensors measure the sample’s thickness while you enter its weight, and the device checks whether the dimensions are consistent with the selected alloy’s density. This is a second, independent check, and it is particularly useful against tungsten-core counterfeits, since tungsten’s density is almost identical to gold’s.
No chemicals and no ongoing calibration maintenance are needed in normal use, and the testing is non-destructive.
Because the measurement relies on an electromagnetic field passing through the item, non-metallic packaging such as plastic does not block it, while metal packaging does, which is why the “no metal in the packaging” rule matters.
What Counts as Packaging You Can Test Through?
✓ Typically Fine (Non-Metal)
- Plastic coin cases and capsules
- Coin flips
- Plastic holders
- Sealed assay packaging that contains no metal
✗ Not Suitable
- Metal containers, tins, or boxes
- Packaging with metal layers or metal components in the test area
If you’re unsure whether a particular package contains metal, check it, and when in doubt, confirm with Telos Instruments or follow the device manual’s guidance.
Good Practice When Testing Through Packaging
Testing through packaging is a strength, but a careful routine gets the most from it.
- Check the paperwork first. Compare markings, serial numbers, and certificates against the item and the seller’s description.
- Select the correct alloy on the device before testing.
- Place the item consistently on the sensor, following the device’s guidance for the wand or sensor arm.
- Run resistivity first, then density (PRO and Investor), and compare the readings.
- Weigh the item where you can. A certified balance supports the density test and is a basic check in its own right.
- Treat unexpected results as a prompt to investigate, not as a verdict. If a reading is unclear and you are entitled to open the packaging, testing the bare item can help clarify.
- Record the result with your purchase documents.
Which PMV Model Should You Buy?
All three models can test through non-metal packaging. They differ in testing methods and intended use.
PMV Original
Includes Small, Large, and Bullion wands. A good entry point for personal investors who want reliable resistivity testing. Tests through non-metal packaging. 2-year warranty.
View PMV Original →PMV Investor
Adds density testing, an adjustable sensor arm, and a full keypad for larger personal holdings. Tests through non-metal packaging. 2-year warranty.
View PMV Investor →PMV PRO
The business-use model, with an optional External Bridge for higher-throughput verification. The right choice for dealers, coin shops, and refiners. Tests through non-metal packaging. 2-year warranty.
View PMV PRO →| Feature | PMV Original | PMV Investor | PMV PRO |

| Best for | Personal investment (entry) | Personal investment (larger holdings) | Business use |
| Resistivity testing | Yes | Yes | Yes |
| Density testing | No | Yes | Yes |
| Adjustable sensor arm (up to 10mm) | No | Yes | Yes |
| Full keypad | No | Yes | Yes |
| External Bridge option | No | No | Yes (optional) |
| Tests through non-metal packaging | Yes | Yes | Yes |
| Jewellery testing | No | No | No |
| Warranty | 2 years | 2 years | 2 years |
Pairing the PMV With the Right Complementary Instruments
A PMV is strongest as one layer in a verification routine. Telos Instruments supplies the other layers too.
Certified Precision Balances
Accurate weight feeds the density test and is a basic check by itself. Telos Instruments supplies Adam Equipment and Kern & Sohn balances.
XRF Gold Analyzers for Jewellery
The PMV does not test jewellery. For jewellery and scrap, use the Terra Scientific Aurora 900 benchtop analyzer, or the Pi900E or EulerX 900 / 900S handhelds. XRF reads the surface and near-surface layer without damage.
Pen-Probe Tester
The GemOro AuRACLE PRO gives fast screening of jewellery at the counter, though it needs a small test point and is a screening tool rather than a final verdict.

Frequently Asked Questions
Yes. PMV devices can test through plastic cases, coin flips, holders, and sealed assay packaging, as long as there is no metal in the packaging.
No. Metal in the packaging interferes with the electromagnetic measurement, so the item must be tested outside metal containers.
Not for non-metal holders. The PMV is designed to test through them, so you can verify without breaking the seal.
No. Testing is non-destructive and uses no chemicals.
The device is designed for testing through non-metal packaging. As a matter of good practice, treat an unexpected or unclear reading as a reason to investigate further, including testing the bare item where that is possible.
All three: the PMV Original, PMV Investor, and PMV PRO.
No. PMV devices are for coins and bars only. Use an XRF analyzer such as the Aurora 900, Pi900E, or EulerX 900 / 900S for jewellery.
The PMV PRO, which is the business-use model and supports an optional External Bridge for higher-throughput verification.

Final Thoughts
If you hold or trade gold coins and bars, the ability to verify them through packaging is one of the most useful features a verifier can have, because it protects both your confidence and the item’s certified value. The Sigma Metalytics PMV range does this for any non-metal packaging, across all three models, without chemicals or damage. Choose the PMV Original to start, the Investor for larger personal holdings, or the PRO for business use, and pair it with a certified balance and, for jewellery, an XRF analyzer. As the exclusive distributor in the UAE and GCC, Telos Instruments can demonstrate the PMV on your own packaged coins and bars before you decide.
