Available from Hylec Controls , the concrete test hammer is an easy to use test instrument. Concrete test hammers can be used for quick and approximate measurement of the resistance to pressure of manufactured concrete products.
The concrete test hammer work by measuring 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 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 is can be established by the concrete test hammer, with 20% of actual.
Specifications of the concrete test hammer conforms to EN 12504/2 and ASTM C 805 for non-destructive testing of strength of mortar, light concrete etc. Energy 0.883 Nm, measuring range 5 to 25 N/mm2.
