Detailed Overview

A 4 MHz Twin Crystal (TC) UT probe with a specialized design (TSTARC) for enhanced near-surface performance. It is used for high-resolution thickness gauging and corrosion/pitting detection on metallic surfaces. The probe is a high-detail, sharp-focus solution for precision near-surface NDT.

A highly specialized, high-resolution twin-crystal angle probe for detecting flaws near surfaces and corners.

• This probe combines the high resolution of 4MHz with a twin-crystal design and an angled beam, making it ideal for detecting flaws in fillet welds, nozzle radii, and other complex geometries where near-surface sensitivity is paramount.
• The design minimizes interference from the probe contact zone.
• The product is a specialized twin-crystal shear wave ultrasonic angle beam probe, often contoured.
