The Sigma Metalytics Precious Metal Verifier (PMV) PRO Mini is a compact yet powerful tool that can assess and verify a precious metal sample in seconds with a wireless connection to your tablet or mobile device (not included) without affecting the coin or bullion in any way. No chemicals are used and no physical damage is done to the coin or bullion being tested. This handy, easy-to-use device can assist in identifying “fakes” and provide peace of mind to coin collectors, bullion investors, pawn shop owners, jewelry stores, and more, about their precious metals acquisitions. This item is not returnable.

The Precious Metal Verifier is used to measure the bulk metal in a bullion bar or coin and ensure that the metal matches the electrical characteristics that would be expected of it. A WiFi connected tablet or mobile phone device (Apple or Android) or Windows computer (not included) with the Sigma Metalytics App installed is required to get readings with the PMV PRO Mini.

Easy To Use:

• Step 1: Install the “Sigma Mini” or “Sigma Metalytics” App found in the Apple App Store or Google Play Store on your tablet or phone (not included)
• Step 2: Turn on the Sigma Metalytics PRO Mini
• Step 3: On your tablet or phone, go into WiFi settings and connections and connect to the “sigma####” network
• Step 4: Open the Sigma Mini app and calibrate device
• Step 5: Use the menu to select the metal type you are testing
• Step 6: Place sample coin or bar under bridge arm and press sensor bar down to make contact
• Step 7: Get a reading within 4 seconds! If the indicator arrow on your screen is within the “green zone”, the sample is within expected range for the selected metal alloy type

Unlike in other testing methods, plating and surface features do not significantly impact the unit’s ability to measure the underlying metal. Using electromagnetic waves that penetrate deeply into the coin or bar, plating and surface features are largely ignored, and the main body of metal assessed. The Verifier can see through plastic cases and bags, so numismatic coins do not need to be removed from slabs or protective holders.

Different sized sensors are used for different sized samples. The main PMV bridge arm sensor can be used for large samples, like 1-ounce coins and bars. To measure smaller objects one of three external wands is connected to the main unit via a cable. The large wand is used for coins weighing between 1/4-ounce and 1 ounce. The small wand can be used for smaller samples, such as 1-gram bars and CombiBars, 1/10-ounce coins, and the like. The Bullion Wand will penetrate the surface of gold and silver bars to a depth of 2 mm (.08 in).

The user selects the metal that the sample is expected to be. The Verifier sets the value of that metal’s resistivity to the center of the bar display. The bar display has brackets that show the expected range of the reading for the selected metal. So, for example, if the user selects pure gold as the metal, and pure gold is placed on the sensor, a value within the green zone of the bar display will be obtained. Virtually any other metal with a similar weight will fall far outside this range. If the actual reading does not correspond to the expected reading, an arrow will show up on the bar display.

Many standard metals are stored in the Sigma Mini App and can be selected by the user. For example, for gold coins the user can select pure gold, 22 K gold, 90% gold, or American eagle gold; for silver, pure silver, sterling silver, 90% silver. and Britannia silver. Pure platinum, palladium, rhodium, and copper also have stored values. Each of these coin and bullion metals will produce a unique reading on the Precious Metal Verifier. Even small changes in alloy make a big difference in the readings on the Precious Metal Verifier.
