Model WAB-1000 Computer Control Hydraulic Servo Bolt and Nut Tensile Testing Machine

Functions & Applications:

Computer control Hydraulic Universal Bolt and Nut Testing Machine is suitable to test various metallic bolt and nut for tension strength. It can be capable of testing the characters of bolt and nut on physical & technology properties. It has single space compact structure which is assembled with servo hydraulic resource, electric driving system, control system and hydraulic loading system. It is simple, easy to operate and widely used in works, laboratories and high schools for material properties research and quality control. Equipped with the computer & Software & printer, it can control the test procedures as the set programs, and can also display, record, process and print the test results and can draw test curves automatically in real time. The machine complies with standards ISO, ASTM, EN, JIS, GB, etc
