Digital Cupping Tester

According to the international standard ISO1520 and the national standard GB9753-88 design and manufacture of QBJ type coating cupping tester is suitable for evaluating the color paint varnish and related products coating (single layer or supporting system coating) in the standard specified experimental methods, indentation test, so that the gradual deformation of the coating resistance to cracking or resistance to the separation of the coating from the metal substrate performance, assessment of the coating pass or fail. Can also gradually increase the depth of indentation, in order to determine the coating just appeared cracking or began to separate from the substrate of the minimum depth.

Technical Parameters：

1、Diameter of indentation:20mm
2、Maximum depth of indentation:10mm
3、Precision of indentation:0.05mm
4、Digital display index value:0.01mm
5、Maximum indentation force:1000N
6. Specimen specification:70mm*70mm*0.3mm~1.25mm
