Concrete hardness test hammer

No.: 03040010 Standard: GB9138-88Purpose and Character WTC-Model H Concrete Rebound Test Hammer is an instrument applied in non destructive testing of structure and compressive strength of concrete. It is to come up with the strength of the concrete component by testing surface hardness of concrete component. The instrument working method is as follows. The fixed value clicks the string, which starts the rebound hammer. When the hammer contacts the other side surface of rebound shaft on the testing surface of the tested concrete component, rebound impact is produced. And with the effect of the impact, the rebound hammer pushes the sliding pointer travel towards the reading which is to be obtained.
