Premium Materials:
The crack monitoring kit is made from high-quality transparent acrylic, offering a clear and accurate measurement grid. It includes full instructions, crack record sheets, screws, and adhesive for quick and easy setup.
Precise Measurement:
The X–Y axis is marked with a ±1 mm (±0.04") scale and ±0.5 mm (±0.02") resolution. It measures up to ±20 mm (±0.79") horizontally and ±10 mm (±0.38") vertically for reliable tracking of crack movement.
Reliable Monitoring:
This simple yet effective analogy device is designed to measure horizontal and vertical crack movement on flat surfaces, helping you monitor structural changes over time.
Versatile Application:
Ideal for 2D manual crack tracking, it allows you to observe, record, and analyse how cracks develop over specific periods.
Smart Design:
The tell-tale gauge features two overlapping plates: a calibrated base plate marked in millimetres and a transparent top plate with a fine crosshair cursor. As cracks shift, the cursor moves along the scale, making it easy to record changes accurately on the included tracking sheets.
