schmidt hammer 
1.Needle length: 20mm 
2.Elastic pullback spring length: 61.5mm 
3.Strike hammer stroke: 75mm 

Application:

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 hammeron a piston which rests against the surface of the concrete products.The Greater the resistance of the concrete, greater is the rebounded impact. By reading this rebound impact on a scale and relating it to curves on graphs supplied with the instrument, the resistance to compression in MPa or PSI can be found, with 20% of actual.
