Rebound hammer HT-225 has 2.207J impact energy, measuring the compressive strength, easy to use, 100 to 600 kg/cm² measuring range, 66 x 280 mm dimensions, 1Kg weight. The compressive strength of concrete elements, bridges and other structures is tested with a concrete test hammer, which is particularly popular in civil engineering for NDE evaluation
