Efficient tracking The grout monitor features a two-panel design with a transparent cover plate for clear visibility. The thin wire cursor moves in relation to the scale to capture accurate data on gap openings and closures. Results are recorded on the included log sheet when two nails are removed, providing a simple method to document changes over time. Enhanced measurement capability This grout monitor provides precise measurements with a resolution of 0.5 mm (0.02 inches). It offers a horizontal range of 20 mm (0.79 inches) and a vertical range of 10 mm (0.38 inches). The device includes an XY axis scale of 1 mm (0.04 inches) and a scale wire to support high accuracy in readings. Portable and easy to use Designed for portability, the grout monitor uses newly designed mounting posts to enable accurate placement without glue or complicated steps. The improved stability and user-friendly design make attaching two plates quick and convenient, supporting efficient on-site use. Material and readability Built with high-quality ABS and acrylic materials to ensure durability and stability. The construction supports reliable readings, and the design makes it easy to read the data during use. Use scenarios - Tile and grout installation: monitor and document uniform gap openings along horizontal grout lines to ensure consistent spacing across a range of joints. - Post-installation verification: track any changes in gap size after grout curing to verify stability and identify settling or movement. - QA in tiling projects: apply the monitor to verify alignment and spacing over multiple panels, ensuring consistency across larger surfaces.
