Overview

The TJ-UT210 uses a dual-element pitch-and-catch probe arrangement for fast, stable readings. It is designed for in-service wall thickness and corrosion thinning monitoring of pipe, tanks, pressure vessels and steel structures.

The probe both transmits and receives, so readings stay stable even on rough surfaces without relying on couplant.

FAQ

Does the gauge need couplant?+

In dual-element mode the probe transmits and receives simultaneously, so no couplant is needed — simply place it on the surface. Single-element separated probes do require couplant for signal coupling.

Can I measure through a coating?+

Not for base metal thickness directly; you would need coating mode or to measure the coating first. Pairing the TJ-UT210 with the TJ-CT coating gauge allows combined coating and base metal measurement.
