MZ-5000A and MZ-5000B micro-computer control electronic universal testing machine adopt micro-computer control, new door style frame, sensor force test system, frequency conversion stepless speed variation and synchronous belt drive. The structure is novel, digital processing is accurate. It is simple to operate, and convenient to maintain. The machine is high precision and multi-purpose testing machine for testing mechanical property of metal or non-metal materials, and can accurately test the physical property data of kinds of materials during stretching. It has three show windows of force value ( force peak value ), displacement value and range, can be equipped with micro-printer. It can be applied to science and technology department, university and college and industrial and mining enterprises to analyze the mechanical property and test production quality. MZ-5000A shows force value, and MZ-5000B shows force value and displacement value. Technical Parameters: 1. Maximum Range: 50KN Speed: within ?% of the show value. 2.
