HS 900GW is based on the piezoelectric effect. The contact type ultrasonic oblique beam single crystal probe with a proper angle wedge generates ultrasonic guided waves in metal components, which is suitable for rapid detection of materials such as tubes, rods, and plates.
Guided wave detection has a long transmission distance, high detection accuracy, low attenuation, high efficiency and low cost.
→ Portable integrated design, weight is only 2.3KG
→ Transmitting piezoelectric: 800V±10%
→ New process operation mode, easy to learn and use
→ Multiple views display, A+B; the image is more intuitive
→ The special guided wave probe is used in combination with the pull-wire encoder, with good detection accuracy and high efficiency
