产品介绍
Application:
It is used to test the strength of the large heavy concrete component especially the water conservancy project, sea port, railway tunnel, mine, bridge, overloading highway, airstrip and so on.. It is designed specifically for the non-destructive testing of hardened concrete structures.
Features:
1. Shell uses super hard aluminums, protect hammer from damage on site work and prolong use life.
2. Center rod uses imported material, high precision and wear proof
