The OS-120 Pendulum Hammers are designed to test on softer material such as light weight concrete, gypsum boards, fresh concrete and the mortar of joints in brickwork. Their unique design allows easy to handle measurements on vertical and horizontal surfaces.

Schmidt OS-120 is the only rebound hammer worldwide working with the pendulum system, thus it must not be loaded on the test surface. The larger plunger surface on the Schmidt OS-120PT allows tests on soft concrete starting with a compressive strength of 1 MPa.
