Sonatest compression wave transducers are ideal for flaw detection, defect sizing, and thickness gaging. Ideally suited on corroded and pitted surfaces and for ultrasonic inspection of coarse-grained and attenuative materials such as duplex and stainless steel. The durable range includes single and twin types, automated: for use in scanners, high-temperature models, and creep wave transducers: optimized to detect near-surface defects.
