With SIGMASCOPE GOLD you can verify the authenticity of gold objects quickly and non-destructively. The handheld device reliably determines the presence of foreign materials such as tungsten, which can be found in forged gold bars or gold coinage. The mobile instrument is equipped with a cable probe that enables measurements even through protective or packaging foils. This prevents damage to valuable samples. SIGMASCOPE GOLD is available in two versions: SIGMASCOPE GOLD C is optimized for the analysis of gold coinage, while SIGMASCOPE GOLD B is optimized for testing the authenticity of gold bars.
