A wide range of mechanical crackmeters (jointmeters) are produced in order to satisfy all client’s requirements.

The removable extensometer allows the measurement of relative movements between two reference pins positioned across the joints (fissure). The extensometer, which comes with its own portable, storage case, has a precise sliding rail with length adjustable base. Uniaxial and 3-D (triaxial) mechanical jointmeters are also available to monitor joints and cracks. The movements between the two anchors are obtained with mechanical dial gauges.

Simple and inexpensive, the TT-1 tell-tale crack monitor installed across a fissure allows the crack survey to be conducted in two directions..
