Description
Overview
GAOTek’s High Precision Digital Ultrasonic Flaw Detector can quickly, easily and without damage, accurately detect, locate, evaluate and diagnose various defects inside the workpiece such as cracks, welds, pores, sand holes, inclusions, folding, etc. It has been applied for electric power, petrochemicals, boiler and pressure vessels, steel structures, military, aerospace, railway transportation, automobile, machinery and other fields. It is an essential instrument for the non-destructive testing industry.
Features
- Measurement display mode for multiple wave forms
