Products Description
The HS 710 is a portable handheld digital ultrasonic detector that supports A-scan, B-scan, and C-scan imaging modes. Its ultra-fast sampling rate improves the accuracy of echo displays and positioning. The device allows for remote real-time positioning, WiFi connectivity, and cloud-based detection via a mobile app.
It is particularly effective for A-ultrasonic (A-Scan) inspections, such as those for butt welds, fillet welds, circumferential welds on pipes, longitudinal welds on pipes, and more.
In addition to standard ultrasonic testing, the HS 710 also includes a specialized TOFD testing function. This feature provides full imaging scans of workpieces between 12mm and 50mm in thickness, ensuring complete coverage with just one scan.
Performance Feature
●The 400MHz sampling frequency enhances the ability of waveform reduction degree.
●It enables cloud-based detection through WiFi internet connectivity.
●Its resistive touch screen is oil and water-resistant, providing reliable touch sensitivity.
●The device is equipped with B-scan, C-scan, TOFD, and guided wave functions, giving users the option to select the appropriate mode as required.
