The micro-fy hand magnet is a portable, lightweight and robust magnetic tester for magnetic particle testing on steel, iron and other ferromagnetic components. It is particularly suitable for hard-to-reach areas such as weld seams or pressure vessels and is easy to handle thanks to its ergonomic design. The hand magnet is supplied in a practical carrying case and is ideal for industrial use in shipbuilding, mechanical engineering, the energy and petrochemical industries as well as for surface and near-surface defect testing.
