Advanced Metal Authenticity Technology:

Inside Sigma Metalytics Precious Metals Verifiers

Introduction

Sigma Metalytics is at the forefront of precious metal testing with its state-of-the-art Precious Metals Verifiers. These devices are engineered using advanced verification systems and innovative metal authenticity technology to help investors, collectors, and professionals detect counterfeit coins and bars quickly and non-destructively.

The Technology Behind the Verifiers

The core of Sigma Metalytics’ technology lies in its ability to measure the resistivity of a sample. By assessing the unique resistivity signature of a metal, the verifier can confirm whether the alloy composition of a coin or bar matches its expected profile. This non-destructive testing method uses electromagnetic waves that penetrate beneath surface coatings, plating, and even plastic packaging.

Key technical features include:

  • Electromagnetic Scanning: Uses electromagnetic waves to take a reading of a metal or alloy.
  • Resistivity Measurement: Compares the measured resistivity of the sample against pre-stored values for various metal alloys.
  • Density and Specific Gravity Testing: Some advanced models also verify specific gravity by analysing the physical dimensions and weight of the sample.

The Verification Process

The verification process is designed for simplicity and speed. Here’s how Sigma Metalytics Precious Metals Verifiers work:

  1. Sample Placement: The coin or bullion bar is placed on the device’s sensor or connected via an external wand. The verifiers can even test through plastic cases, making them ideal for numismatic coins.
  2. Metal Selection: The user selects the expected metal type (such as pure gold, sterling silver, platinum, or palladium) from a stored list of standard values.
  3. Measurement: The verifier emits electromagnetic waves that penetrate the sample. It quickly measures the metal’s surface and, in advanced models, its full-depth resistivity.
  4. Analysis: The device compares the measured resistivity to the expected range for that particular alloy. Any deviation triggers an alert on the display, indicating potential counterfeiting or inconsistency in the alloy composition.

Underlying Analytics and Benefits

The advanced analytics integrated within Sigma Metalytics devices offer multiple layers of verification:

  • Depth Analysis: Advanced models use dual sensors—one measuring surface resistivity and another gauging the underlying metal—to detect even further into discovering inserted or layered metals.
  • Dimension Verification: By cross-checking the weight with the measured dimensions, the system verifies that the density of the sample is consistent with the stated metal type.
  • Rapid Results: With results available in less than one second, users can quickly authenticate precious metals without resorting to chemical tests or destructive methods.
  • User-Friendly Interface: The verifiers are designed for ease of use, allowing even novice users to operate the system with minimal training.

These benefits ensure that users are equipped with a reliable tool to prevent fraud and maintain the integrity of their precious metal investments.

Conclusion

Sigma Metalytics has revolutionised the way precious metals are authenticated. Their innovative use of metal authenticity technology and advanced verification systems provides a fast, accurate, and non-destructive method for testing bullion coins and bars. Whether you are a seasoned investor or a casual collector, these verifiers offer peace of mind by ensuring that every piece of precious metal meets the rigorous standards required for authenticity.
