Ultrasonic Flaw Detector(7)

DLD-C1230 A/B/C/D Tube Bar C Scan




● Structure internal and surface corrosion detection
● Crack depth, shape and detection of crack sources
● Detection of layered defects
● Inspection of defects inside metal materialsand composite materials

The C-scan system has quality stability, durability and reliability.
The high-resolution color LCD display is equipped with fast analog real-time measurement system to provide detailed waveform information. The high-speed screen refresh rate (above 70 Hz) enables real-time display of defect echoes. The quick keyboard, simple and clear menu structure make the human-computer interaction more friendly, and the instrument operation is very convenient. Various output interfaces make the application more extensive and use more flexible.
