As long as both plates can be firmly fixed to either side of the crack, the tool will deliver accurate readings.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I read the crack gauge measurements?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the crack gauge monitor suitable for outdoor use?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What surfaces can the acrylic crack gauge monitor be used on?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.
