Mechanical crackmeter
The mechanical crackmeter consists of two components. One component is a rigid arm that spans the crack. It holds a precision-ground reference block. The other component holds the dial gauge so that it can obtain measurements of three sides of the reference block. The tell-tale crack monitor is a simple, plastic device that is be installed across fissures to provide measurements in one or two directions.
