Air-Coupled UT

Applications of ultrasonic testing vary, ranging from weld inspection to wall thickness measurement and the detection of discontinuities such as invisible cracks, inclusions, voids and other discontinuities in metals, plastics, ceramics and composites.

Experienced material testers have supervised the development of SONOTEC flaw detector and probes focusing on simple operation procedures and high sensitivity while simultaneously providing a robust design.

We offer a wide range of corresponding SONOSCAN probes. Select the suitable probe from our product program according to your application.

In addition to our standard products, we also manufacture customer-specific solutions.

Contact-free Testing with Air-coupled Ultrasound


Already during the material development of modern composite materials such as glass or carbon fiber reinforced plastics (GFRP, CFRP) and ceramics it is necessary to detect internal structures and discontinuities fast and reliably.

Research institutes, industrial development laboratories and quality assurance departments of production facilities highly appreciate a contactless, high resolution inspection. The performance of the transmitter receiver system is very important to penetrate these highly attenuating materials. The ultrasonic transducers, the scanning area and the software can be adapted to the specific geometry and material composition of the test object.

These high requirements can be fulfilled with the new and modular SONOAIR inspection system for laboratory and quality assurance applications.


Extensive Software Library SONOSTUDIO


> Display of the measurement results as A-, B-, C- or D-Scan

> Storage of the complete A-scans for every measurement point during the testing process

> Repositioning of the measurement gates after the inspection

> Individual signal processing algorithms (e.g. for filters)
