EEC-39RFT Portable RFT/ECT Instrument

EEC-39RFT 4-frequency & 2-channel eddy current instrument is designed with full digital electronic technique, eddy current technique and micro technique to meet different testing demands It integrates ECT and RFT functions 4 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-39RFT is widely used for heat exchanger tubing It can get good result while testing defects and measuring wall thickness of in-service tubes (Cu, Ti, Al, Fe 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
