EEC-35++ 2-frequency & 2-channel eddy current instrument is designed with full digital electronic technique, eddy current technique and micro technique to meet different testing demands The two frequencies can help to get higher testing coverage, high testing frequency can be well used for surface inspection while low frequency has high sensitivity for subsurface defects With tube sheet function, EEC-35++ can get good result while testing defects and measuring wall thickness of in-service tubes (Cu, Ti, Al etc ) It’s widely used in departments of nuclear energy, electric power, petrifaction and spaceflight With mixing units, it can suppress disturbing signal caused by baffle, indent, sediment, and cold-working Designed with full-digital technique, users can easily store testing data and parameters and read them out for local testing
