For aircraft maintenance and repair, the portable, Centurion NDT-1100 simplifies eddy current lift-off and operation for the nondestructive testing of wheels, struts, propellers, airframes, hubs and engine components. The instrument has an automatic balance/null feature that substantially reduces setup time for manual operation. By moving the probe and turning a phase control knob on the front panel, lift-off can be completed in seconds. The iPad-sized instrument with an LCD screen will locate surface and near-surface defects and conductivity changes in magnetic and nonmagnetic materials, and can cover about 85% of eddy current testing applications.
