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.
