Type N Schmidt Concrete Test Hammer from NDT James

SKU: WM250


Concrete Test Hammer w/case Economical strength testing of hardened concrete and hardness testing of materials. The manual concrete test hammer is the traditional instrument used for the non-destructive testing of hardened concrete. This instrument provides a quick and simple test for obtaining an immediate indication of concrete strength in various parts of a structure.  All concrete test hammers measure the surface hardness of the material they are testing; this is then correlated to concrete compressive strength. The manual concrete test hammer (aka: rebound hammer, schmidt hammer, swiss hammer, sclerometer) is the most widely used non-destructive instrument for compression strength determination. Features:
