The Model ED-400M Eddy Current Test Instrument determines and locates cracks and flaws faster more economically and environmentally safer than magnetic particle inspection. It is a self-contained electronic instrument that offers exceptional sensitivity, making it ideal for quick, reliable crack detection. Setting up and operating the ED-400M could hardly be easier. Once the probe is electronically balanced, the operator slides the probe over the inspection piece, keeping an eye on the easy-to-read meter. The meter needle then deflects, pinpointing the location of the flaw. Audio and visual alarms can also be set to alert the operator. Unlike other eddy current instruments, it is not affected by changes in background magnetic permeability. Thus, the tester requires no adjustment when inspecting for defects through surface rust, oxides, paint or other coatings. In addition, minor movements in probe alignment during inspection do not seriously affect the meter reading. With applications ranging from weld inspection and maintenance to receiving inspections and process control, it is widely used to compliment or replace magnetic particle inspection methods. It measures 5” high x 9” wide x 6” deep and weighs 5.3 pounds. For more information visit www.centurionndt.com or call (630) 736-5500.
