TesTex uses a variety of state-of-the-art electromagnetic techniques to scan for defects in both ferrous and nonferrous materials and structures.

LFET Products

Low Frequency Electromagnetic Technique (LFET) products are used to inspect storage tanks, other convex or concave ferrous surfaces, as well as nonferrous metal tubing/piping surfaces.

RFET Products

Remote Field Electromagnetic Technique (RFET) products are used to quickly and accurately inspect ferrous tubing found in heat exchangers and drum-to-drum boiler generating banks.

BFET Products

Balance Field Electromagnetic Technique (BFET) products are used to detect surface and sub-surface cracking in welds and base metals.

ECT Products

Eddy Current Technique (ECT) is used to quickly and accurately inspect non-ferrous metal tubing from the tube internal dimension (ID).


TesTex has enhanced ultrasonic (UT) inspection for many different applications, including tank shells, UT prove-ups, finned tubes and waterwalls.


TesTex produces standard and custom probes (and calibration tubes) for all of its ID (internal dimension) inspection equipment.

“I want to recognize J__ S__________ for an outstanding job he did for us during the 37 boilers re-certification. J__ preformed IRIS testing in the mud drum and from what I was told, this is one of TesTex most tedious tests. This required a skilled and experienced technician. While J__ was here he had difficulties with his equipment and only a proficient technician would know how to overcome theses problems and still make the scheduled deadline. From what I understand, he also used this time to train his helpers with hands-on training for this inspection method. J__ kept me up to date with his progress and I felt very reassured that the job was getting done correctly. Once the job scope was completed, J__ provided me with a preliminary report and then I received the final report which was just a few days later.”
