LANGRY’s GZII Testing Anvil is essential for accurate rebound hammer calibration. Placed on a rigid horizontal surface, it ensures precise calibration vertically or horizontally. The average calibration value of the N-type concrete rebound hammer (2.207J) is [R] = 80±2. Furthermore, its Rockwell hardness of HRC 58-62 guarantees durability. The testing anvil is usually kept in a dry and dustproof place to prevent corrosion. The test surface shall not be knocked against at will to ensure the inspection tool’s standard state.
Product Features
- High-quality steel and tool steel construction.
- The connecting surfaces of the anvil core and body, which fit together using Morse taper No. 4, are finely ground.
- Durable enough for 5,000-8,000 bounce tests, with surface grinding capability for reuse.
- Corrosion-resistant design for long-lasting performance.
