DL-5KN computer-controlled tensile testing machine is a high-precision load testing machine, equipped with liquid crystal display, using microprocessor control and integrated, digital measurement and control technology, and can be processed and printed information.DL-5KN computer-controlled tensile testing machine is suitable for conveyor belt whole core dumbbell-like tensile testing performance, etc. With the corresponding tooling, it can automatically obtain the maximum tensile strength, elongation stress, elastic modulus, constant elongation stress, constant stress elongation and other parameters. Equipped with the corresponding tooling, it can automatically obtain the maximum test force, tensile strength, elongation stress, modulus of elasticity, constant elongation stress, constant stress elongation and other parameters. The testing machine is powerful, accurate in data processing, simple in operation and convenient in use and maintenance. It meets the test requirements of GB/T 528-2009 "Determination of Tensile Stress and Strain Properties of Vulcanized Rubber or Thermoplastic Rubber" and MT914-2008 "Fabric Whole-Core Flame-Retardant Conveyor Belt for Coal Mining" and MT830-2008 "Fabric Laminated Flame-Retardant Conveyor Belt for Sulfur Coal Mining" standards.
