Why You'll Love It
- High-Quality Acrylic Construction: Crafted from premium acrylic material, this crack monitor is durable, sturdy, smooth, and wear-resistant — built to last through long-term monitoring projects.
- Crystal-Clear Readability: The transparent top plate features a precision cross-hair cursor, while the bottom plate is calibrated in millimetres, making readings quick and accurate at a glance.
- Dual-Axis Monitoring: Tracks both horizontal and vertical crack movement on flat surfaces, giving you a complete picture of how a crack is evolving over time.
- Clever Two-Plate Design: Two overlapping boards — a calibrated base plate and a transparent overlay — work together so you can record and compare crack displacement with ease.
- Compact & Portable: Measuring approximately 10 × 3 × 0.9 cm (3.94 × 1.18 × 0.35 in), this lightweight tool fits easily in a toolbox, bag, or pocket.
- Practical for Many Surfaces: Ideal for monitoring cracks and deformation in walls, ceilings, masonry, concrete, plaster, and more.

Frequently Asked Questions
Q: What surfaces can the acrylic crack gauge monitor be used on?
A: The crack gauge monitor is designed for use on flat surfaces including walls, ceilings, concrete, masonry, plaster, and similar building materials. It is ideal for tracking crack movement in both interior and exterior structural surfaces.
Q: How does the two-plate design of the crack monitor work?
A: The crack gauge consists of two overlapping acrylic plates. The bottom plate is attached to one side of the crack and features a millimetre calibration grid. The transparent top plate is attached to the other side and has a cross-hair cursor. Any movement of the crack causes a visible shift in the cursor position relative to the grid, allowing you to measure displacement accurately.
Q: Is the crack monitoring gauge reusable?
A: Yes. The durable acrylic construction means the gauge can be removed, cleaned, and reused on different cracks or monitoring sites as needed. It is built to withstand long-term use without breaking or warping.
Q: What unit of measurement does this crack gauge use?
A: The base plate is calibrated in millimetres, allowing for precise, small-increment tracking of crack movement over time — making it suitable for professional structural monitoring as well as DIY home inspections.
