Sclerometer Schmidt Hammer 225

Art: А00191

Schmidt Hammer 225 is a device to measure the elastic properties or strength of concrete or rock, mainly surface hardness and penetration resistance.

The hammer measures the rebound of a spring loaded mass impacting against the surface of the sample. The test hammer will hit the concrete at a defined energy. Its rebound is dependent on the hardness of the concrete and is measured by the test equipment.

Schmidt Hammer 225 is easy to use instrument. You can use it indoor and outdoor.
