Submerging the part in water gives the most uniform, repeatable acoustic coupling of any UT method — no variable contact pressure, no couplant gel to reapply. SDI's immersion line ranges from compact benchtop units for labs and universities to large production tanks built for 24/7 operation.
Four platforms cover the full range — from lab-scale training systems to heavy-duty industrial tanks built to support turntables and rotators.
Compact Benchtop Immersion System
A small-footprint immersion platform suited to labs, universities, and R&D environments teaching the fundamentals of ultrasonic testing.
| Configuration | Benchtop, compact tank |
| Typical use | Labs, universities, R&D |
Production Immersion System
Full-size production tank with integrated control console, built for workhorse operation in busy NDT labs and Tier 1/Tier 2 supplier facilities.
| Configuration | Full-size production tank |
| Control | Integrated console |
| Typical use | High-volume production NDT labs |
Immersion System for Pulse Echo Plate, Billet & Composite Inspection
Widely used for production inspection of metallic raw material, advanced composite, and metal-bonded components. High-speed contour following is available for back-wall-following plate inspection or pulse-echo inspection of complex laminate parts.
| Configuration | Large plate immersion tank |
| Inspection mode | Pulse echo, contour following available |
| Typical use | Plate, billet, composite production inspection |
Heavy-Duty Industrial Ultrasonic Immersion System
SDI's largest-capacity industrial immersion tank — heavy welded box-section frame with an extensively reinforced base for supporting turntables and rotators, paired with SDI's advanced PC-based contour-following motion control and acquisition package.
| Configuration | Heavy-duty industrial tank |
| Frame | Reinforced box-section, turntable/rotator capable |
| Typical use | Large production components |
