The SIGMASCOPE GOLD B measures the conductivity of gold bullions. A faked item contains inclusions or alloy components from other materials like tungsten or copper and this will change the conductivity. Even small inclusions or changes in the alloying lead to a significant change of the conductivity, which will be reliably recognised by the SIGMASCOPE GOLD B.
Only three quick and easy steps are necessary in order to verify the gold bullions:
- Mass-determination with scales.
- Verifying the dimensions.
- Test with the SIGMASCOPE GOLD B.
