Concrete Test Hammer
Measuring range 10 to 70 N/mm² compressive strength (below 25 N/mm² type P is better suited). Impact energy = 2,207 Nm. Rebound values are read from a scale. Testing the compressive strength of a prefabricated concrete girder. Rebound values are recorded by an assistant who will calculate mean values and read compressive strength values from a conversion diagram.
