Schmidt Rebound Hammers For Concrete Strength And Rock Testing

Schmidt Rebound Hammers For Concrete Strength And Rock Testing The Concrete Rebound Hammer is in accordance with technical regulation of JGJ/T23-2001, used for testing of concrete compressive strength within the scope of 10-60Mpa, with the system standard energy of 2.207J, and value indicating system of pointer direct reading. Our concrete resiliometer has been approved as "Recommended Product for Engineering Construction" By the Ministry of construction.Hammer shell with special treatment, high hardness, long-term use of non-draw traces in raw materials processing technology, precision design other aspects of life are greatly improved. Technical Datas: Length of pointer: 20.0±0.2 (mm) Friction of pointer: 0.65±0.15 (N) Sphere semi diameter at the end of the flip rod: 25±1.0 (mm) Rigidity of flip tensioned spring: 785.0±40.0 (N/m) Location of flip hammer's hook release: "100" at the scale mark Work length of flip tensioned spring: 61.5.0± 0.3(mm) Strike length of flip hammer: 75±0.3(mm) Hop location of the flip hammer: "0" at the graduated scale Fixed value of steel anvil: 80±2 ( Controlled between 80-81) Features Light saving 2/3 forces compared with counterpart products Flexible, inexpensive, power-free, easy to master Button applies stretching technics and is not easy to fall off Pointer is easy to adjust friction The first choice applicable for on-the-spot NDT
