Play it safe with gold.

The special devices for mobile and non-destructive authenticity checks of gold, precious metals and coins.


Distinguishing counterfeit from originals
Possible measurement through
plastic packaging
Variable depths of indentation
suitable for the thickness of the object to be measured

Tactile authenticity check for gold and precious metals.

With the compact SIGMASCOPE® GOLD B and SIGMASCOPE® GOLD C handheld measuring gauges, you can reliably determine the authenticity of precious metals and thus detect counterfeits reliably and non-destructively. Distinguish counterfeit gold bars from pure gold, check large pieces of jewelry such as a pocket watch for authenticity or detect expensive counterfeits of the precious metal with the help of electrical capability. In short: you know immediately whether the object to be measured is genuine.

Suitable for the gold industry.

Prevents purchase of fake coins and gold bars

Easy to use.

Operation via high-contrast touchscreen display with user-friendly user interface

Well equipped.

Perfect complement to your Fischer XRF instrument

Your safety.
