How do the GoldScreenSensor and the GoldScreenPen work?

The GoldScreenSensor and the GoldScreenPen measure the conductivity of your precious metal object using eddy current testing. In this process, the coil of the respective device induces a magnetic field that generates eddy currents within the object. This allows the conductivity to be determined, which the testing device displays in megasiemens per meter. Each precious metal has a specific conductivity, which is why any impurity would be immediately detected during a measurement. If a precious metal is alloyed with another metal or has a core made of a foreign metal, our devices will indicate this by comparing the target value with the actual value.
