Shore rubber hardness testerIt is an instrument for measuring the hardness of vulcanized rubber and plastic products, which comes in three forms: Type A, Type D, and Type C. Type A and Type D are respectively suitable for testing the hardness of low to medium hardness and high hardness rubber materials. C-type is suitable for testing the hardness of shoe micro porous materials made of rubber and plastic containing foaming agents when the compression ratio is 50% and the stress is above 0.049MPa. This hardness tester complies with the relevant provisions of GB/T531, GB2411, HG/T2489, and JB6148.
