With the SIGMASCOPE® GOLD B you can reliably and non-destructively check the authenticity of gold bars up to a thickness of 17 mm and a weight of up to around one kilogram.

With the SIGMASCOPE® GOLD C, you can check the authenticity of coins and thin bars weighing up to around 100 grams in a non-destructive manner.

The advantage of non-destructive conductivity measurement lies in materials of the same density: inclusions of foreign materials such as tungsten can be reliably detected.

Precise and non-destructive measuring of precious metals, coins and gold in the laboratory or retail store in a matter of seconds.

Description

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

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 pocket watches for authenticity, or detect expensive counterfeits of precious metal with the help of electrical conductivity. In short: you'll know immediately whether an object to be measured is genuine.

Prevents purchase of fake coins and gold bars
