The measurement results are compiled into a report automatically or, if preferred, with a single button press.

• Crack detection in components
• Detection of blowholes and coarse grain formation
• Detection of geometric deviations
• Detection of brake pad detachments
• Detection of delamination
• Cost and time savings thanks to low personnel requirements
