Conductivity-based authenticity inspection! Non-destructive and extremely rapid testing is possible.
Fischer's "SIGMASCOPE(R) GOLD" is a device suitable for measuring conductivity from precious metal coins to large gold bars. Its operating principle is based on non-destructive testing using the eddy current method in accordance with DIN ISO 21968. Through phase-sensitive measurement signal analysis, non-destructive measurements can be performed even under non-conductive shielding films, such as plastic packaging. The penetration depth of the eddy currents can be selected according to the density of the object being measured. 【Features】 ○ Capable of precisely measuring the conductivity of coins → Reliable authenticity testing based on conductivity ○ Inspection depth of up to 18mm (up to 36mm when combining front and back) → Can verify the authenticity of alloys or pure gold → Measurements can be taken even through protective sheets For more details, please contact us or download the catalog.

basic information
【Features】 ○ Can quickly and reliably detect any type of imitation (such as imitation gold coins or gold bars) using a non-destructive method. ○ Identifies precious metal blocks or coins based on conductivity. → Utilizes the physical property that pure gold and various alloys have different conductivity. ○ Capable of inspecting up to 18mm in depth (up to 36mm if measuring both sides). ○ Can verify the authenticity of alloys or pure gold. → By measuring both sides, it can capture the entire depth of a gold bar. ○ Even if there are inclusions of base metals with similar density (such as tungsten), they can be clearly recognized and identified as imitations. ○ Measurements can be taken even through a protective sheet. ● For more details, please contact us or download the catalog.
