Greiner Vibrograf Magnotest II

The Magnotest II magnetism sensor measures the magnetism of an object, including watches and small parts.The number of red lights indicates the magnetism of the object, with two red lights indicating weak magnetism and four lights indicating strong magnetism.

To measure magnetism and also demagnetize the object, we recommend the Greiner Vibrograf Magnomaster Plus, VIB-MAGNOMASTER/PLUS.
