Automated Scratch Tester


An automatic scratch-test system for characterizing hard material layers, the FISCHERSCOPE ST200 is a progressive load scratch tester for analyzing the adhesion and cohesion strength of coatings according to ASTM C1624, ISO 20502, and DIN EN 1071-3. Easily check the adhesion and cohesive strength of layers ≥1 μm thick. The instrument is ideal for use in development, quality assurance, incoming goods control, and production monitoring.
