The precise measurement of wall thickness plays an important role in the quality control of tubes and metal sheets. The non-destructive ultrasonic method can be used for this. This can detect irregularities outside of the tolerance zone and precisely measure the tube or sheet thickness.

PLATEPROOF: The PLATEPROOF testing system uses ultrasonic technology to reliably check coil and sheet for discontinuities and automatically determines their number, dimension, depth, and position. In addition, the sheet thickness can be determined with the pulse echo technique.
