The DMITER Crack Monitor Set combines two professional crack-tracking tools—a standard tell-tale crack monitor and a corner crack monitor—designed for precise measurement of structural movement in concrete, masonry, foundations, interior corners, and building surfaces. Engineered for high accuracy and long-term monitoring, this kit ensures reliable data for engineers, surveyors, inspectors, and construction professionals. Both monitors feature a dual-plate system with a millimeter-graduated base plate and a transparent cross-hair cursor plate, enabling accurate detection of crack displacement in both horizontal and vertical directions. With ±1mm tick marks, ±0.5mm discrimination, and support for corner angles from 70° to 180°, this set provides comprehensive coverage for straight cracks and internal/external corners. Installation is simple with screws and adhesive. Each monitor is built from durable, high-clarity polymer material and includes installation instructions and a crack record sheet—making it easy to track structural changes over time. Whether for home assessments, structural inspections, or long-term building monitoring, the DMITER crack monitor kit offers a professional, accurate, and versatile solution.
