Structural defects cause serious damages and collapses. Ultrasonic testing provides information on the strength and uniformity of concrete, rock, composites, ceramics, wood, refractory materials. It can also be used to detect and localize voids, honeycombs, delaminations, pipes, cracks and defects. The ultrasonic pulse echo (UPE) technology extends ultrasonic pulse velocity (UPV) applications to objects where access is restricted to a single side. Pundit offers the most versatile range of ultrasonic testing instruments that are ergonomic and portable.
