Description

AVONGARD - TD11 Displacement Tell-tale 

The Avongard Displacement Tell-Tale monitors horizontal and displacement movement where there is a “step” across a crack due to displacement or “out of plane” movement. 

The Tell-Tale consists of three components. A base plate (not calibrated), a top plate (calibrated) and a graduated ruler. The ruler is removed from the gauge when not taking a measurement but used to measure the relative movement in the plates.

  • Calibrated in millimetres.
  • Fix using Screws and Adhesive (not included but available as accessories).
  • Supplied with full instructions and Crack Record Sheet.
  • Weather-resistant.
