Immersion Ultrasonic Wall Thickness Testing of Small Diameter Tubes - YUSHI PM5 Gen3 Ultrasonic Thickness Gauge

This video presents a practical inspection demonstration of wall thickness measurement for small-diameter tubes adopting the water immersion ultrasonic technique with the YUSHI PM5 Gen3 ultrasonic thickness gauge.

Traditional contact ultrasonic testing often encounters insufficient coupling and unstable echo signals when measuring curved, thin-walled small bore tubes. The immersion coupling method improves ultrasonic propagation efficiency, acquiring stable, repeatable thickness readings during non-destructive testing.

The YUSHI PM5 Gen3 thickness gauge supports real-time A-scan display, making it a reliable solution for quality control of heat exchanger tubes, capillary tubing and precision tubular components.
