Jointmeters are mechanical measuring instruments for the surveillance of movements of joints and cracks in rock, concrete, masonry and at steel constructions. The movements can be measured in 1 to 3 directions according to the chosen type of Jointmeter.


Jointmeters consist of a left and right part which are fixed on both sides of the joint using a temporary template. The movements are measured by a portable Setdeflectometer (mechanical or electrical dial gauge).
