Tube Inspection NDT System EEC-2004S is designed with eddy current testing (ECT), endoscope, remote field testing (RFT), low frequency testing (LFT), metal magnetic memory (MMM) and magnetic flux leakage (MFL) are all included in this instrument. The all-in-one design makes the small body with strong function.
This intelligent multifunctional electromagnetic tester makes the inspection much easier, faster and more accurate. Eddy current testing (ECT) with endoscope, remote field testing (RFT), low frequency testing (LFT), metal magnetic memory (MMM) and magnetic flux leakage (MFL) are all included in this instrument. The all-in-one design makes the small body with strong function.
Designed with 3 mixing units and tube sheet mapping makes this instrument widely used for inspection of small pipeline, heat exchanger tubes and boiler tubes, for both carbon steel and non-ferrous materials.
Inspection settings for different applications can be stored in files and simply called up when needed. Testing data can be saved and called up for replay.
