Description

The UFD-F720 is a digital ultrasonic flaw detector (UT) for non-destructive testing of materials. It is used to detect, locate, evaluate, and size internal discontinuities (e.g., cracks, inclusions, weld defects) using A-scan display, DAC/AVG functions, and AWS D1.1 support. Suitable for inspections of welds, metal structures, and industrial maintenance, with waveform recording and data export via USB.
