Digital Rebound Test Hammer

Description of Digital Rebound Test Hammer

DIDAC Export offer an optimum quality Digital Rebound Test Hammer. The offered product is manufactured and designed using the finest quality components with the help of contemporary technology. The offered product is delivered to our buyers only after its proper checking on different such as dimensional accuracy, performance, finish, etc. The rebound number determined by this method can be used to assess the uniformity of concrete in situ, to delineate zones or areas of poor quality or deteriorated concrete in structures. This test method is not intended as an alternative for the compressive strength determination of concrete, but with suitable correlations already saved in the instrument, it provides an estimate of the in situ compressive strength. The hammer may be used for comparative testing, referenced against a concrete with known strength or against a concrete verified as conforming to a particular strength class. The rebound hammers measure the rebound of an anvil impacting a plunger in contact with the concrete surface. This new working principle is equivalent to the traditional measurement of maximum spring length after the impact, but it provides the following benefits:

Higher accuracy and stability of the readings not affected by wear and tear

Setting of the impact angle no longer required

A check of the device reliability can be performed during each impact, even without the calibration anvil.
