After affixing, temporary pegs are removed so plates move independently. Spigots on both plates enable exact measurement to 0.1mm with calipers. A second Crack Monitor may be positioned for monitoring in three dimensions.

Monitoring crack widths in concrete buildings, bridges, and roads is easy and reliable with this Concrete Crack Monitor. The overlapping upper plate is transparent and marked with a red crosshair cursor. The white bottom plate measuring grid is marked in millimeters. Opening and closing of the crack is monitored in 1mm increments. Monitors are affixed with user-supplied screws and adhesive.
