LDCJ-300 Microcomputer Controlled Tensile Stress Relaxation Testing Machine
This product is suitable for testing equipment for measuring the relaxation properties of metal materials at room temperature. The product complies with GB/T10120-2013 "Metal Stress Relaxation Test Method".
Features:
1.The host machine is of horizontal structure with moderate height and easy operation. The load-bearing pedestal is a welded structure with high rigidity and light weight.
2.The universal prestressed through-hole jack is adopted, which has strong versatility and is suitable for prestressing. Applicable to tensioning Ovam clip group, anchor DM type heading anchor and LEM type cold casting anchor.
3.The piston of the working jack is double-acting, which can realize quick return.
4.Using a high-flow high-pressure pump, the loading speed can be controlled by a manual valve.
5.Full digital measurement and control device, stable performance, high measurement and control accuracy.
6.With force and displacement automatic clearing, automatic calibration function.
7.The force measurement resolution is high and does not change in the whole process, and it is not divided into files.
8.The whole machine is equipped with 6 round hole backing plates.
