Magnetic Field Meters
Residual Field Testing Device M-5
A simple handy device to determine residual magnetism in steel parts. The scale with zero point in the middle has a range of 20 units.
Full deflection corresponds to 20 G or 16 A/cm.
Dimension: 50 mm Ø, 22 mm high
Weight: 60g incl. case

In place of continuous current, steel parts are magnetized or demagnetized using direct current pulsing. In order to reveal cracks or material separations such as fusing or forging defects, these are ideally sprayed with a fluorescent test media, allowing evaluation under a UV LED test lamp even under daylight conditions per EN ISO 9934-1 and documentation with a digital camera.
Using DC-pulse technology instead of continuous current offers the following advantages:

• High performance of testing devices ( testing current up to 25.000 A)
• Much lower energy consumption
• Compact dimensions of testing devices
• Low weight of testing devices

That way mobile testing is possible. MT-testing takes place next to the component. That makes testing of large components easy. MT-testing device and cables connect quickly to the components to be tested and are testing large areas at the component at once. Slow manual scanning of a part for example with a magnetic yoke does not apply.
Less operator fatigue
Using the compact, lightweight and high performance mobile HPT testing equipment it is possible for the tester to concentrate on his own task in evaluating the visual indications. This can reduce the proportion of complaints considerably. The parts can be subsequently demagnetized directly on site if necessary.
