**Product Description:**
This advanced hydraulic servo universal testing machine is ideal for industrial, academic, and research applications. It comes equipped with a Lenovo computer, HP printer, large gauge electronic extensometer, optical encoder, and comprehensive test software. The system allows users to easily perform tensile, compression, and other types of tests, while ensuring accurate results with multiple curve outputs such as force-displacement, stress-strain, and more.
The machine is designed with a unique oil cylinder under mounting structure, offering both tensile and compression testing capabilities. The transmission system uses a motor reducer, chain drive, and screw mechanism to adjust the testing space efficiently.
The hydraulic system includes a filter screen, pump, and oil valve to ensure smooth operation, while the control system supports custom test parameters, open editing, and detailed reporting. Safety features include overload protection and stroke limit control, making it a safe and efficient choice for any lab or workshop.
The machine also includes a specialized steel strand extension device, which helps ensure that the specimen breaks in the middle, improving test success rates. A variety of fixtures are available, including a stretch fixture, to meet different testing needs.
