List-Magnetik Takes On Ferromaster from Stefan Mayer Instruments

List-Magnetik, a Germany-based developer, manufacturer and dealer of magnetic meters, has taken over the manufacturing and sales of the magnet permeability meter Ferromaster from Stefan Mayer Instruments GmbH & Co. KG. 

The Ferromaster is now exclusively available from List-Magnetik, based in Leinfelden-Echterdingen, who sells the instrument under its own brand. The meter determines the relative magnetic permeability or conductivity of feebly magnetic materials and workpieces with a permeability between 1.001 and 1.999. The permeability is measured by touching the workpiece with the probe tip and reading the result from the display.

Typical applications are non-destructive testing of materials such as quality control of stainless steel, material selection for ion-beam equipment, detection of material defects induced by mechanical or thermal stress. 

Mayer Instruments, located in Dinslagen, designs and manufactures low-noise magnetometers, field cancelling systems and magnetic permeability meters.
