The HS Q7 digital ultrasonic flaw detector is a flaw detector with an appearance comparable to that of a mobile phone. It is light and beautiful, which can meet the testing needs of various scenes.
Vertical display is palm work, and horizontal display is wrist work.
→ Handwriting touch, hot key button dual operation mode
→ All-metal casing, quality assurance, quality enjoyment;
→ USB communication interface, C5 type probe interface, convenient and fast;
→ 1000 pieces wave storage, at least 4 hours of dynamic waveform sustainable storage; professionally designed for new specifications;
→ Weld groove form, accurate positioning and real display;
→ The crack height measured, and the height of the defect is automatically calculated by the diffraction wave.
