Rock test hammer GEOSTONE

Mechanical Rock Test Hammer The GEOSTONE mechanical test hammer is the only instrument available on the market today that can provide correlation between the rebound hardness scale values measured and the compression resistance of the rock tested. Using the GEOSTONE rock rebound hammer to analyse rock is a valid non-destructive testing method that can be carried out on site to evaluate the surface hardness of the material. Non-destructive testing methods are employed to evaluate, within the limitations of the procedure itself, the compression resistance of natural rock materials on site. The GEOSTONE rock rebound hammer is a valuable and easy to use instrument that produces accurate and reliable data about the quality of the material tested.
