The PMV PRO + External Bridge represents the pinnacle of technology from Sigma Metalytics. It is an advanced professional tester with an external probe and bridging that allows you to verify even large volume ingots (such as 250g, 500g or 1000g) while measuring the full depth of the material - up to 50mm through the metal.
This kit provides the highest level of accuracy currently available in non-invasive precious metal testing. Ideal for refiners, wholesalers, investment houses and advanced collectors.

Accuracy verified by banks and refineries
Why choose PMV PRO + Bridge?
If you require the highest level of protection against counterfeits, comprehensive diagnostics and the ability to test even the largest bars without having to unpack or disturb them, this model is your number one choice. Used by banks, refineries and the largest traders on the market.
What else can it do compared to cheaper models?
Higher accuracy thanks to multi-frequency measurement
Possibility to measure larger bars (including kilogram bars)
Connecting external probes for specialized measurements
Better readability and control thanks to larger display
Greater measurement depth than Original and Investor
Advantages of PMV Original over the competition
Non-invasive testing – no damage to the coin or bar
Instant result – measurement takes only a few seconds
High accuracy – technology used by exchanges and metal buyers
Easy to use – anyone can do it without special training
Tests through capsules – no need to handle the sample
Affordable solution – ideal for smaller redemption houses, retailers and private investors
While competing detectors often only work on the surface or based on weight and size, PMV PRO analyzes metal structures across the depth of the ingot and eliminates counterfeits even in exactly imitated pieces.
How can I use PMV?
Simply turn on the device, select the alloy you want to test from the built-in database, then place the sample on the sensor. If the sample is consistent with the selected alloy, the display will show a result within the expected range.
How does PMV resistance testing work?
The patented technology tests the characteristic resistance of a sample. Essentially, a sensor in the device generates a very small electromagnetic field and measures how your sample bends that field. We know how a real sample would bend the field, and the device compares your sample's test results to a known good result. If they are consistent, it is considered passable.
How does PMV density testing work?
The PMV Investor and PRO can test the density of samples using their built-in sensors (or an external bridge when using the PRO). There is a sensor above and below the sample that can measure the thickness, the user enters the weight and the device knows the density of the selected alloy. So there is only one variable left: the diameter of the coin (or the length/width of the column). The device will then display how large the sample should be, and if your sample matches the size displayed, then the density of the sample is consistent with the selected alloy.
Can PMV test through packaging?
Yes! All of our devices can test through plastic cases, holders, plastic pockets. If there is no metal in the case, it should be possible to test through plastic. Some cases are more difficult to test than others, but these are rare.
