The Concrete Test Hammer is a measuring tool for testing the strength of concrete. The Concrete Test Hammer measures strength according to the Schmidt principle. According to this measurement method, the quality of concrete can be measured with the Concrete Test Hammer. Thus, the Concrete Test Hammer finds its essential application in the construction and in the construction sector. The Concrete Test Hammer is also suitable for testing hardness of rolled paper.  The built-in mechanism on the hardness tester always ensures the same impact energy of 2.207 Nm.
