Manual Digital Cupping Tester

The principle is to press the test plate tightly from the top with a fixed ring with holes, and then slowly press the test plate with a spherical head from bottom to top, forming a hemispherical protrusion deformation in the middle of the fixed ring; Visually observe whether there is cracking or detachment from the substrate on the raised test panel through a magnifying glass, and use the height of the protrusion at the initial occurrence of cracking or detachment from the substrate as an evaluation indicator. The operating surface adopts a tilted layout for easy observation; Adopting a side rocking hand to lift the spherical head for smoother operation; The display adopts an LCD screen, which simultaneously displays the cup protrusion value (current maximum top appreciation value) and the shaking value (indicating the current position of the top with positive and negative values); It can be used upon startup, and there is no requirement for conductivity on the test board, nor does it need to be calibrated to zero every time it is turned on; It is also possible to continue the jacking process after retreating.
