The SD-UFD681 is a digital portable ultrasonic flaw detector designed for fast, damage-free detection, location and evaluation of internal defects (cracks, inclusions, pores) in welds and materials. The 5.7-inch IPS display offers a wide viewing angle with a 60 Hz refresh rate, and the ergonomic housing is water- and oil-resistant.
Auto-calibration covers probe zero offset, probe angle (K value) and material velocity. Up to 500 test channels and 1000 defect reports can be stored, and inspection results are exported as PDF reports.
Features

- 5.7-inch IPS high-brightness display, no viewing angle, 640×480, 60 Hz refresh
- Auto-calibration of probe zero offset, probe angle (K value) and material velocity
- Real-time screenshots and PDF flaw-detection reports to USB drive
- Peak-hold and edge trigger modes; echo gate and loss-of-echo gate
- 500 test channels and 1000 defect reports storage
- Straight, angle, dual-crystal and through-transmission probe support
