HS 710 is a handheld portable digital ultrasonic detector that can realize A-scan, B-scan, and C-scan imaging modes, and ultra-high-speed sampling, making echo display more fidelity and positioning more accurate. It can realize remote real-time positioning, WiFi connection and cloud detection through mobile phone app.
It is suitable for A-ultrasonic(A- Scan) inspection, such as butt weld, fillet weld, pipe circumferential weld, pipe longitudinal weld, etc.
In addition to the conventional ultrasonic testing function, TOFD testing function is specially integrated, which can meet the one-time full coverage imaging scanning of 12-50mm workpiece.
→ 400MHz sampling frequency, higher waveform reduction
→ Can connect to the Internet via WIFI to achieve cloud detection
→ Resistive touch screen, oil and water proof, sensitive touch
→ With B-scan, C-scan, TOFD, guided wave function, it can be arbitrarily selected
