  The 200N Zhongchuang Manual Spring Tension and Compression Tester, is mainly used to do tensile and compressive test of all kinds of spiral springs. Measure the load of spring at a certain deformation, or measure the deformation of spring at a certain load. The machine is mainly applied in spring manufacturing units, low voltage electrical units, power machinery units, universities and research institutes laboratories and other units.
