Adhesion Tester AT measures traction force that will be necessary to remove a defined area of a coating from a subsurface. Surface condition of the testing material is of significance regarding measurement of extraction force or adherence. Owing to the opportunity of self-alignment of the several measurement heads unevenness of surface will be compensated. Traction force will be shown on the LC display and can therefore give information about adherence to substrate material. Additionally, the adhesion tester has a traction velocity display to guarantee realization of testing according to ISO / AST standardization. Tester can be used in fields like input and output control, production as well as research and development. The adhesion tester is splash-water resistant, dust resistant and protected against vibration. Hydraulic hand operated pump allows application in almost every position. A special advantage is internal measurement value memory, for instance, if the adhesion tester wil
