Unlike generic tools, these are calibrated for detailed tracking of movement, ensuring you can monitor changes caused by thermal expansion, settlement, or seismic activity. The durable polymer construction withstands varied environmental conditions, providing reliable data for construction projects, renovations, or ongoing building maintenance across India. Imported directly from authorized US retailers, these monitors ensure you receive a genuine tool for critical structural assessments. **Ideal for Engineers and Homeowners, Skip if You Need Digital Data** — These tell-tale crack monitors are perfect for civil engineers, construction professionals, and homeowners needing to track crack progression on walls and concrete structures. They are ideal for manual record-keeping and visual analysis. However, if you require automated digital data logging, wireless transmission, or integration with smart building systems, these analog monitors may not be suitable. For such advanced needs, consider digital crack monitoring solutions. ## How to use 1. Clean the flat surface around the crack where you intend to install the monitor. Ensure the area is dry and free from debris for proper adhesion or mounting. — Prepare the Surface 2. Carefully position the tell-tale monitor over the crack, ensuring the crack runs through the center. Secure the monitor to the surface using appropriate adhesive or fasteners as per standard construction practices. — Install the Monitor 3. Once secured, remove the two small pegs from the monitor. Note the initial position of the hairline cursor on the millimeter scale. This is your baseline reading for future comparisons. — Remove Pegs and Record Initial Reading 4. Periodically check the monitor and record the cursor's position on the scale. Compare new readings to the initial baseline to quantify any crack opening or closing, documenting changes over time. — Monitor and Record Movement ## Product details | Field | Value | |---|---| | Application | Attach to flat surfaces with cracks to monitor movement. | | Measurement Method | Manual reading of cursor position against millimeter scale. | | Usage Frequency | As needed for ongoing structural monitoring. | | Cost per use | 5 monitors at ₹6,853 — ₹1,371 per monitor | | Shelf life after opening | N/A (Durable tool) | | Contraindications | Not suitable for digital data logging or automated systems. | | Allergens / common irritants | N/A | | Brand | Mountlaser | | Model Number | LFY | | Style | 5PCS | | Material | High-quality Polymer | | Horizontal Range | ±20 mm (±0.79 inches) | | Vertical Range | ±10 mm (±0.38 inches) | | Tick Mark Increment | ±1 mm (±0.04 inches) | | Discrimination | ±0.5 mm (±0.02 inches) | | Item Weight | 50 grams (0.02 pounds) | | Package Weight | 0.22 kilograms (0.49 pounds) | | Package Dimensions | 20 cm x 14.3 cm x 3.5 cm (7.87 in x 5.63 in x 1.38 in) | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### How do I use the Mountlaser Tell-Tale Crack Monitor? To use the Mountlaser Tell-Tale Crack Monitor, attach it to a flat surface over a crack. Remove the two pegs. As the crack opens or closes, the hairline cursor on the transparent top plate will move relative to the millimeter calibration scale on the bottom plate. Record the cursor's position to track crack evolution over time. ### What is the measurement range and accuracy of these crack monitors? These crack monitors offer a horizontal range of ±20 mm (±0.79 inches) and a vertical range of ±10 mm (±0.38 inches). They feature ±1 mm tick marks and provide a discrimination of ±0.5 mm (±0.02 inches), allowing for precise measurement of crack movement. ### Are these crack monitors suitable for use in India? Yes, these Mountlaser Tell-Tale Crack Monitors are suitable for use in India. They are durable analog tools that can effectively measure crack movement in various structural conditions. All customs duties and GST are included in the price, and they are shipped via ExpressBox tracked delivery. ### Can these monitors detect changes in crack width over time? Absolutely. The design of the tell-tale allows you to record the cursor's position on the millimeter scale at different times. By comparing these readings, you can accurately monitor and quantify any changes in crack width, whether it's opening or closing, over the duration of your observation. ### What is the difference between this and a digital crack monitor? These Mountlaser monitors are analog devices, meaning they rely on a physical scale and cursor for measurement, requiring manual recording. Digital crack monitors typically use electronic sensors to automatically log data, often wirelessly, and may offer more advanced analysis features. These analog versions are simpler, require no power, and are very cost-effective for manual tracking. ### How to buy an original Mountlaser Tell-Tale Crack Monitor in India?
