Twin Element Probes
Twin Element probes can be used to take thickness measurements
on both Coated and Un-Coated metals.

Corrosion – heavy corrosion will absorb and scatter the ultrasound
signal so there is often only enough ultrasound reflected back to
the probe to provide a single echo.
Identifying Single or Twin Element Probes
You can easily identify each type of probe by looking at the probe
face;
