Sonatest Ltd


We provide a comprehensive range of portable ultrasonic flaw detectors to give you flexibility and performance in your non destructive flaw detection processes. Our digital ultrasonic flaw detectors cover the full spectrum of operator requirements from entry level models to those powerful enough for use in high-spec application environments.

Our non destructive flaw detectors are perfect in industries such as aerospace and automotive.

Phased Array

We supply phased array (PA) ultrasonic equipment. Phased array techniques allow the user to control parameters such as beam angle and focal distance to create an image of the test part, enhancing defect detection and speed of testing.

Typical applications of phased array equipment include:

  • Weld Inspection
  • Crack Detection
  • Corrosion Mapping
  • Aerospace and Composite Testing
