Efficient tracking - The monitor uses two panels and a transparent cover plate for an innovative design. The thin wire cursor moves with the scale to capture accurate data on gap openings and closures. Results are recorded on the included log sheet when two nails are removed. High-precision monitoring - Resolution: 0.5 mm (0.02 in) - Horizontal range: 20 mm (0.79 in) - Vertical range: 10 mm (0.38 in) - XY axis scale: 1 mm (0.04 in) - Scale wire supports high accuracy Easy installation - Newly designed mounting posts fix the monitor easily and precisely - No glue or complicated assembly steps required - Increased stability and comfort during setup Durable and readable - Advanced technology delivers precise results - ABS and acrylic materials provide durability and stability - Design enables easy reading of data Use scenarios - Tile installation in bathrooms or kitchens to monitor uniform grout gaps - Masonry or concrete repair projects where grout alignment affects performance - New construction flooring or wall tiling where precise gap monitoring ensures consistency
