L Type Rock Test Hammer

The L type rock test hammer is spring drives the flip hammer; the flip hammer knock on the surface of brick through flip rod; the restoring force produced after instant transform makes the hammer rebound back, and the pointer indicates the instance of rebound, which is one of a indicators evaluating brick’s compressive strength and predict the compressive resistance and label of the brick.
It is used for testing strength of ordinary bricks with NDE, still for testing strength of light skeletal material concrete and other light materials.
