Geo Stainless Steel Discs

Stainless steel discs used as reference points for crack monitoring with calipers. Pack 100 When measuring a crack with calipers, steel discs are placed either side of the crack. Over time the crack may move, with the steel discs bonded to the surface, a caliper can be used to measure the movement. When using this type of method, a measurement will not indicate the x or y movement, just the distance apart. If the x and y needs to be recorded, it is advisable to utilise a tell tale. 7mm Stainless steel discs used as reference points for crack monitoring with calipers. Pack of 100 discs
