Standard Crack Gauge Crack gauges can be used to monitor horizontal or vertical movement across a crack on a flat surface.

Displacement Crack Gauge The displacement crack gauge monitors horizontal and displacement movement where there is a step across a crack due to displacement of “out-of-plane” movement.

Concrete Crack Gauge for Corners The corner crack gauge uses a hinged mounting bracket to allow monitoring of cracks in corners with angles between 70° and 180°.
