HEF-C35RFT RFT/ECT Eddy Current Tester for Heat exchanger and
Boiler tube with Tube sheet mapping
HEC-C35RFT eddy current instrument with remote field technology
option is a new generation eddy current instrument. HEC-C35RFT with
full-digital, multi-frequency, multi-channel is a versatile system
offering a comprehensive array of electromagnetic testing
techniques available on a single instrument HEC-C35RFT can be used
to accurately and efficiently inspect both non-ferromagnetic and
ferromagnetic tubing materials for flaws such as pitting corrosion
vibrations wear steam erosion and cracking.
HEC-C35RFT combines the advanced testing capabilities of the
HEC-C35RFT with a highly sensitive remote field technology option,
makes the instrument an ideal solution for a broad range of tubing
applications in the petroleum chemical and power generation
industries. Where inspection of both non-ferromagnetic and
ferromagnetic materials is required. In contrast to other
ferromagnetic tubing inspection, the HEC-C35RFT provides not only a
more complete --100% coverage with inner and outer surface
discontinuity detection, but also thickness measurement -- in a
fraction of the time.
