Dependable Analysis Support Clear measurement grid on a quality acrylic sheet provides precise markings for dependable crack analysis and tracking, enabling accurate crack monitoring over time. Consistent Tracking Device This crack monitoring device reliably tracks horizontal and vertical movement, delivering dependable performance for regular observation without digital complexity. Accurate Data Recording Two removable pins allow adjustable setup, while records on the chart and cursor show movement, providing a clear and consistent log of crack behavior. Consistent Crack Observation Enables manual 2D monitoring to track wall cracks progressively, delivering precise measurements and dependable evaluation. Key attributes and benefits Material: acrylic sheet with a clear measurement grid for easy visibility and precise marking. Function: dedicated tool for crack analysis, movement tracking, and data recording without digital systems. Setup: two removable pins allow quick and adjustable positioning to fit different wall sections. Data capture: movement is recorded on a chart and cursor, ensuring a reproducible log of crack progression. Performance: manual, 2D monitoring provides reliable observations with minimal setup and maintenance. Use scenarios Structural health monitoring during construction, retrofit, or stabilization projects, where non digital crack tracking is preferred. Post incident or post load testing to observe crack progression on concrete or masonry walls over time. Laboratory or field tests involving crack propagation in test panels, where a clear, repeatable 2D measurement method is required.
