Functional features
Microcomputer control electronic tester is my company developed economical and practical models, this product is made of high strength light bars fixed on the crossbeam and the work table, so as to form the gantry high rigid frame structure, the use of domestic servo motor drive, servo motor drives the beam to move up and down through the transmission mechanism, realize the loading process. The tension compression space is relatively small, and the column spacing is small. Configuration is relatively low. Precision 1.
Microcomputer controlled electronic testing instrument is mainly used to test the mechanical properties of all kinds of metal, nonmetal and composite materials. Precision automatic control and data acquisition system, to achieve the data acquisition and control of the whole process of digital adjustment. In the tensile test, the test material, such as tensile strength, tensile strength, elongation, elongation and other technical indicators. The above parameters at the end of the test, the test parameters set by the microcomputer controller according to the test at the beginning of the automatic calculation, and display the corresponding test results, and automatically save the detection parameters; at the end of the trial after the query display.
Microcomputer control electronic tester is suitable for metal, adhesives, pipes, profiles, aerospace, petrochemical, waterproofing materials, wire and cable, fiber, textile, rubber, ceramics, food, pharmaceutical packaging, geotextile, film, wood, paper and other manufacturing industries as well as the level of product quality supervision department, also for teaching demonstration in the colleges work.
