How are the GoldScreenBox and GoldScreenPen working?

The GoldScreenBox and the GoldScreenPen measure the conductivity of your precious metal object using eddy current testing. The coil of the respective device induces a magnetic field that creates eddy currents in the object. This allows the conductivity to be determined, which the tester outputs in megasiemens per metre.

Each precious metal has a specific conductivity, therefore contamination would be immediately noticeable in a measurement. If a precious metal is underalloyed or has a core of foreign metal, our devices show you this with a target/actual value comparison. The GoldScreenBox additionally gives you the result in the form of a coloured illustration of green, yellow and red.
