Product Data Sheet – MAG 40

MPI Test Bench Unit

The Magnaflux MAG 40 test benches are self-contained, low-cost units that detect and locate fatigue cracks or processing defects using the ‘wet continuous’ method of magnetic particle inspection.

These medium-duty machines are ideal for machine shops, tool rooms, foundries and similar plants where low-volume testing of ferrous components is required.
