Displacement monitoring
Clock-IT — 2 Anchor Dial Extensometer
Help underground teams recognise smaller ground movements with clear, magnified dial readings that support informed ground support decisions.
Monitor ground movement at two depths to better understand changing conditions around underground roadways. The Clock-IT uses large, reflective clock-face dials and a mechanical multiplier to make small movements easier to read during visual inspections. Its lower and total displacement readings help site personnel understand where movement is occurring, track changes over time and inform ground support decisions.
- Two anchors monitor lower and total movement.
- Large reflective dials support visual inspections.
- A 5 x mechanical multiplier magnifies movement at the readout.
- Can be used to monitor movement in roof, ribs and floors.
- Easy installation with no grouting required.
