In the observation of cracks in structures often simple Gipsplomben be used, which can only qualitatively show changes of the crack. If the size and / or direction of the progressive deformation structure is important, you should use our spies crack or crack gauges.
Simple and inexpensive measuring device for measuring crack widths from about 1 mm with an accuracy of 0.02 mm.
Precision scale magnifier with 7-fold magnification for a distortion, pin sharp image.
The measuring wedge allows for a very accurate direct reading of the gap width is in a range of 1 - 11 mm, if the plan has a sufficient depth
Standard model for detecting displacements in two directions (up-down / right-left).
Additional, centered stainless steel plate in the surface with which the resulting crack width can be directly with a caliper (caliper)
For monitoring displacements in three axes (up-down / left-right / front-rear) standing between angle to each other.
