Special Features:

Eddy current flaw detector is compact self contained lightweight instrument for locating cracks and flaws in electrically conductive materials and magnetic and nonmagnetic materials by permeability and conductivity measurement; it has an impedance plane display and motorized bolt hole scanner, external disk drive, ibm-pc based data analysis software; operates on alternating current - 115v AC , 60 hertz - and direct current - rechargeable batteries; it has an operator adjustable frequency range of 50 hz to 3 mhz and automatic self-calibration during set-up including automatic probe balance

Properties:

A non-destructive electromagnetic device which introduces eddy current in a part(s) to be inspected. Changes in the current flow caused by surface variations in the part are reflected into a nearby coil(s) where they are detected and measured by suitable instrumentation which is provided.
