Description

Ecnomic type high strength rebound hammer for concrete testing

The concrete test hammer is an instrument which is easy to use, for quick and approximate measurement of the resistance to pressure of manufactured concrete products. The principles on which it works are based on the rebound impact of a hammer on a piston which rests against the surface of the concrete products. The greater the resistance of the concrete, greater is the rebounded inpact. By reading this rebound impact on a scale and relating it to curves or table on graphs supplied with the instrument, the resistance to comprssion in MPS or PSI can be found.

This HT-225 test hammer submits to standard of GB/T9138-1988 and JJG817-93 and JGJ/T23-2011 and ASTM C 805. HT-225 concrete test hammer is applied to test the compressive strength of building concrete components, bridge and so on.
