Heat Exchanger Tube Inspecton EEC-39RFT

Heat exchanger tube inspecton system with ECT and RFT functions for both ferrous and non-ferrous tubes. Mixing function enables noise signal remove from the support plate, and tube sheet mapping enables to draw the tube layout and to mark the testing result with different colors.  

 

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.
