Concrete Rebound Tester Test strength of concrete material: slab,column,beam,truss. Used in civil engineering,construction,etc

HT-225A Concrete Rebound Strength Tester

Description:

      When testing the strength of concrete, the concrete tester uses a certain elastic force to transit the impact force of an impact hammer to the surface of concrete, its initial kinetic energ redistributes, a part of energy in the form of plastic deformation or residual deformation is adsorbed by the concrete, and another part of energy which is proportional to the surface hardness is transmitted to the impact hammer, making the hammer resile to a certain height, then the strength of the concrete is derived from the proportional relation between the height of resillience and the concrete strength.

     HT-225A concrete strength tester is widely used in civil engineering and construction industry for testing the strength of various concrete members such as: slab, beam, column, truss of normal building strength and bridge. Compared to other nondestructive testers, HT-225A concrete strength tester is an economical and practical instrument.
