EEC-309 is designed with MIMO and OFDM technology, which greatly improves the testing speed of RFT. It is widely applied for high speed tube inspection, heat exchangers inspection, condensers inspection etc. It also enables to inspect defects and check wall thickness at the same time.
This powerful RFT/ECT instrument is designed with 2 channels, 4 frequencies, mixing unit and tube sheet mapping. It's widely used for inspection of small pipeline, heat exchanger tubes and boiler tubes, for both carbon steel and non-ferrous materials.
Tube sheet mapping draws the tube layout and marks the testing result with different colors. Mixing unit removes signal from support plate and leaves only defect signal. Inspection settings for different applications can be stored in files and simply called up when needed. And different types of report can be generated for analysis and record.
