Concrete Rebound Hammer, Portable Resiliometer Tester 10-60Mpa

【High Precision】: portable rebound hammer comes with a scale, the pointer slider adopts an external spring ring structure, which not only facilitates the adjustment of friction, but also ensures uniform friction between the pointer shaft and the pointer slider, with high accuracy and long service life. 【Labor Saving】: The outer shell of the hammer is made of polymer composite material, which is widely used due to its excellent impact resistance, electrical insulation, creep, heat and cold resistance. Now we use it for the shell to get a low carbon and efficient concrete detection tool. 【Easy to Carry】: No need to insert, spring expansion and contraction, strong recoverability. The weight of the product is 0.8kg. 【Wide Application】: It is suitable for testing the strength of general structural members, bridges and various tunnel structural members (slabs, beams, columns, bridges). Please note that this rebound hammer can only test the strength of concrete, not stone or other materials.
