ED-400 Hand Held Flaw DetectorSpecial Features The Centurion NDT Model ED-400 is a portable, solid state eddy current instrument which detects cracks and other surface defects in magnetic and non-magnetic metals. It is compact, lightweight and simple to set up and operate. It provides excellent signal to noise ratio on virtually all metals. • Excellent sensitivity for magnetic material crack detection-provides full scale deflection for 0.008” milled slot. • Extremely high signal/noise ratio. Virtually ignores background magnetic permeability variations. • Excellent lift off compensation eliminates erroneous signals due to surface scale and coatings. • Static or dynamic testing-a wide dynamic range. • Extremely good stability. • Adjustable threshold circuit and audio indicator. • Operates on two ”AA” Alkaline batteries. • State-of-art circuitry--compact, rugged construction. • Simple to set up and operate. • Wide selection of interchangeable probes. • Includes standard reference block for checking equipment performance. • High quality components ensure minimum maintenance. The ED-400 eddy current unit is an electronic test device which will locate surface and near surface discontinuities in magnetic materials. Non-magnetic materials may also be tested. In magnetic steel products and materials, defects as small as 0.005” deep may be detected with ease, if they are open and normal to the surface. The ED-400 is widely used in maintenance, receiving inspection, process control, final inspection and research. Its compactness makes the ED-400 valuable for testi

foundries, heat treat shops, manufacturing plants, steel mills, automotive plants...and wherever accurate data must quickly be obtained, so as to establish product reliability. Operation The ED-400 is a portable, compact, self-contained electronic instrument which offers high sensitivity and simplicity of operation. A differential probe forms two legs of the bridge circuit, which is contained within the instrument. The ED-400 is housed in a high impact resistant ABS enclosure. The unit and standard accessories are packed in a protective carrying case. The standard accessories include a steel...
