For measuring displacement of adjacent surfaces
Crack meters are designed to measure displacements across cracks and joints typically in buildings, bridges, dams, pipelines and rock formations and are available for measuring movement in one (1D) or three axes (3D).
Joint meters are ideal for monitoring movement of joints in mass-concrete structures. Typical applications include abutments, slabs, foundations and retaining walls, tunnels or shaft linings, arch, gravity and buttress dams.
Data can be obtained using a portable readout or connected into a data logger for automatic monitoring.
