Remote field testing is the best way to inspect ferromagnetic heat exchanger tubing material such as carbon steel.

Welded on a flexible stainless steel shaft, each driver and receiver modules are designed to be resistant and waterproof to manage a whole heat exchanger U-bend tube in a single pass. It is designed to manage tight bends.

The probes are particularly well suited to detect common defects (corrosion, erosion, wear, pitting) and to inspect the ferromagnetic tubing in feedwater heaters, heat exchangers, and piping.
