MPI Equipment – Mobile Test Units


If you are testing at a fixed installation, or if you have components that are too large or heavy to be inspected by standard fixed-position MPI equipment, you need one of our mobile test units.

We understand the challenges you face with multiple different test parts, locations and inspection types. We can help you choose from our wide range of units to find the one that is best suited to your needs.

Chain Inspection System

Chain inspection unit

The compact design of our mobile chain inspection unit is ideal for use on-site. It can also be used as a stationary system.

The standard unit is equipped with:

  • Ferrotest 10 or GWH 15
  • foot switch to control the inspection current
  • closed magnetising coil Ø 350 mm (working height of the coil approx. 840 mm)
  • test liquid drip tray with test liquid pump (contents approx. 5 litres)

For part numbers and more information, see the Product Data Sheet.

FerrotestFerrotest GWH 40 mobile crack detection unit

Our high-current Ferrotest mobile power packs provide maximum AC magnetising currents from 1000 Amps up to 7100 Amps. The Ferrotest GWH packs provide both AC and HWDC; they generate test currents from 1050 Amps to 7100 Amps.

All Ferrotest units are provided with following built-in standard functions:

  • Constant current magnetisation
  • Impulse current magnetisation
  • Demagnetisation

All Ferrotest units meet the requirements of the following standards and specifications:

  • EN 60204-1:2006
  • DIN EN ISO 9934-3:2002
  • DIN VDE 0100-410:2007
  • DIN VDE 0100-540:2012

For part numbers and more information, see the Product Data Sheet.

IsotestIsotest mobile crack detection unit

Isotest mobile power packs are designed for constant or impulse current magnetisation and are suitable for magnetising parts either with AC or full-wave DC.

They are ideal for use in harsh conditions where the highest reliability is essential, for example, the automotive and aeronautical industries, foundries, forging shops, steel production and processing.

The Isotest range consists of:

  • 30 E for test currents up to 3,000 A DC and AC
  • 60 E for test currents up to 6,000 A DC
  • 100 E for test currents up to 10,000 A DC

For maximum testing safety, all three models feature a constant current control and an (optional) current flow detection system.
