Clear measurement grid on a durable acrylic sheet enables precise markings for dependable crack analysis and reliable monitoring. Tracks movement in both horizontal and vertical directions using simple analog technology for steady, reproducible results. Chartbased recording with two removable pins and a moving cursor clearly demonstrates crack progression for accurate tracking. Manual 2D crack measurement on walls allows observing changes over time for consistent analysis and progress tracking. Use scenarios: Monitor cracks on residential or commercial walls after seismic events, settlement, or weathering to inform decisions on repairs or monitoring. During construction or renovation, track plaster or masonry movement to verify it stays within expected limits. In historic building preservation, document crack progression over time to support maintenance planning and risk assessment.
