Dependable analysis support The device uses a clear measurement grid printed on a acrylic sheet, providing precise reference points for crack analysis and tracking. This enables accurate crack monitoring over time and reduces measurement ambiguity. Track movement accurately Captures both horizontal and vertical changes with straightforward analog technology, delivering steady, repeatable readings without relying on complex electronics. Ideal for environments where simple, reliable measurements are preferred. Dependable tracking mechanism Progress is recorded on a chart using two removable pins to fix readings, while a cursor visually indicates movement. This setup supports clear, confident crack analysis and progression tracking. Comprehensive crack tracking Supports manual 2D measurements of wall cracks, effectively capturing progressive changes while maintaining steady observation and documentation. 23 use scenarios Construction site monitoring: Track crack development in load bearing walls during building to detect early signs of structural movement and guide timely interventions. Renovation and retrofit projects: Monitor existing cracks to assess whether repairs or modifications affect structural stability during updates. Historic or masonry structure preservation: Perform long term, non invasive crack tracking to document changes over time without introducing complex instrumentation.
