PRO

4 Ways to Measure

The PMV PRO makes four separate measurements to ensure that the sample contains valid metal.

External Bridge

The External Bridge plugs into the PMV PRO and allows for thru measurements on bars between 12.5 and 45mm thick and at least 50mm wide.

 

Wand Attachments

The Small, Refiners, and Large wand plug into the PMV PRO and allow you to measure surface resistivity of samples outside the range of the onboard sensors.

1. Surface Resistivity

The PMV PRO 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.

2. Thru Resistivity

Using two sensors, one above and one 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.

3. Thickness

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.

4. Density

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.

External Bridge

The External Bridge allows for thru measurements on bars between 12.5 and 45 mm thick that are at least 50 mm wide.

Refiners wand

The Refiners wand allows for measurements of surface resistivity for bars thicker than 12.5mm. It measures 60-70% deeper than the Bullion wand that comes with the PMV Original.

Small wand

The Small wand allows for measurements of surface resistivity (like the original PMV) for smaller samples that are at least 8 mm in diameter. It allows for testing of coins down to 1/20 oz and 1 gram bars.

Large wand

The Large wand is used for coins weighing 1/4 ounce and larger. It is useful for rapid checking of many samples in a short time.
