MZ-2000A、MZ-2000B micro-computer control electronic testing machine adopt micro-computer control, sensor force measuring system, stepless speed variation, synchronous belt drive. The structure is novel, data processing is precise. It is simple to operate, and convenient to use and maintain. The machine is high precision and multi-purpose testing machine to test mechanical property of metal or non-metal materials. It can accurately calculate physical property data of materials during stretching, has three display windows of force value (or force peak value), displacement value and range, and can be equipped with micro-printer. Software setting and parameter storage, it also has the function of limit space protection. It can be applied to science and technology, university and college, and industrial and mining enterprises to analyze mechanical property of materials and test production quality.
