Clear Acrylic Crack Gauge Monitor – Precise Wall Crack Measuring Instrument
Keep a close eye on structural changes with this Clear Acrylic Crack Gauge Monitor. Designed for homeowners, builders, and inspectors alike, this compact two-plate instrument lets you accurately track horizontal and vertical crack movement on walls, floors, and other surfaces over time — all without any specialist equipment.
Key Features
- High-Quality Acrylic Construction: Made from premium acrylic material that is durable, sturdy, smooth, and wear-resistant for long-term outdoor or indoor use.
- Crystal-Clear Visibility: The fully transparent top plate features a precision cross-cursor line, making it effortless to read measurements at a glance.
- Millimeter-Calibrated Base Plate: The bottom plate is clearly calibrated in millimeters, enabling accurate tracking of even the smallest crack movement over time.
- 2D Crack Movement Monitoring: Monitors both horizontal and vertical displacement simultaneously — ideal for walls, ceilings, foundations, and masonry surfaces.
- Clever Overlapping Design: Two overlapping boards with a cross-hair cursor on the top plate align over the calibrated base, providing a simple yet highly effective analog monitoring system.
- Compact & Portable: Measures approximately 10 × 3 × 0.9 cm (3.94 × 1.18 × 0.35 inches) — small enough to install in multiple locations around a property.

Frequently Asked Questions
Q: What surfaces can the acrylic crack gauge monitor be used on?
A: The crack gauge monitor is suitable for use on a wide range of flat surfaces, including interior and exterior walls, concrete foundations, brick or stone masonry, plaster ceilings, and structural columns. As long as both plates can be firmly fixed to either side of the crack, the tool will deliver accurate readings.
Q: How do I read the crack gauge measurements?
A: The transparent top plate features a cross-shaped cursor line, while the bottom plate is calibrated in millimeters. Simply note the position of the cross-cursor against the millimeter grid. Over time, any movement of the cursor from its original recorded position indicates the extent of crack displacement — both horizontally and vertically — allowing you to monitor structural changes accurately.
Q: Is the crack gauge monitor suitable for outdoor use?
A: Yes. The high-quality acrylic material is wear-resistant and sturdy enough for both indoor and outdoor monitoring applications. However, for best long-term results in harsh weather conditions, consider protecting the gauge with a weatherproof cover or sealant around the fixing points.
