Abstract: With the development of industry inspection technology, one single function of testing equipment cannot meet the requirements, and it is necessary to combine the advantages of various NDT methods to provide more reliable information. A new system EEC-2008net based on computer network was developed with eddy current, ultrasonic and metal magnetic memory testing technique and conformed to the developing trend of non-destructive testing equipments. The device could reduce false and missed defects, and the switching between different methods was very fast, saved resource and improved the efficiency. The device could also be expanded to be a detection network based on the Ethernet to realize multi-channel detection and sharing the test data with others.
