Sigma Precious Metal Verifier - PRO Unit with External Bridge / No Wands

This Sigma Metalytic Precious Metal Verifier measures a sample's surface resistivity in the same way the PMV Original does. Unlike other testing methods, plating and surface features do not significantly impact the PMV Pro's ability to measure the underlying metal. Using two sensors, one above and below the sample, the PMV Pro measures the resistivity all the way through the sample. This way, the PMV Pro can determine if the metal is consistent throughout the piece and can detect inserted metals. Using the two sensors, the PMV Pro measures the thickness of the sample, even for coins in plastic holders and cases. Plastic and cardboard are invisible to our sensors, which measure the average thickness of the metal between the sensors. With the measured weight entered, the PMV Pro can determine if the density ( specific gravity ) of the sample is consistent with the indicated metal. The PMV Pro does this by making sure that the dimensions of the sample are consistent with the weight, resistivity, metal type, and thickness. The PRO Unit brings unparalleled diagnostic capability to the detection of counterfeit precious metal coins and bullion bars. This verifier greatly enhances the capabilities of the original PMV.

The External Bridge plugs into the multi-pin connector on the main body of the PMV PRO. It allows for thru measurements on bars between 12.5 and 45 mm thick that are at least 50 mm wide. This is the Pro base unit + an external bridge SET
