| UFD-S□D□F□ | 0.5MHz (S1), 1.0MHz (S2), 2.0MHz (S3), 4.0MHz (S5) | C9 (F4) | Ø30mm (D12), 50x57x33mm |






Suitable for detecting defects on parallel surfaces or near-parallel surfaces
Made of metal, sturdy, good shielding performance
Vertical incident longitudinal wave detection by direct probe contact with the workpiece surface
The contact surface is made of hard wear-resistant material, which matches well with the metal acoustic impedance, high sensitivity and strong penetration
