| Abstract: | The YJR-300 Extension Stress Relaxation Testing Machine is mainly used to test the relaxation of the prestress steel wire, steel bar and steel strand. It is easy to realize the stabilized and precise loading without climbing in low speed, and the low noise in high speed. This machine is controled by computer, which obtained customer′s praise because of its first class quality, remarkable performance, excellent service and high performance price ratio. |
