Suitable for rubber, plastic, leather, metal and other materials. It can test the tensile strength, tear strength, elongation at break, peel strength, etc. of rubber. It is equipped with a large deformation extensometer for measuring the deformation of the sample, which is suitable for testing the mechanical properties of materials with large deformation. It is the most widely used instrument for improving formula, incoming material inspection and controlling rubber quality in rubber production. This series of models is mainly applicable to the test of non-metallic and metallic materials with test load less than 2000N.
