Rock Hammer | Geo–Hammer


The DRC research laboratories and the Università Politecnica delle Marche collaborated to produce the DRC Geo-Hammer mechanical rock test rebound hammer.

A user friendly instrument the DRC Geo-Hammer mechanical rock test rebound hammer is placed flush against the sample material and then fires a spring loaded percussion rod into sample material surface. The percussion rod hits the surface and rebounds back into the DRC Geo-Hammer mechanical rock test rebound hammer, this rebound action is then measured by the built in scale; which is measured in Rebound Units (Ru). This measurement is then compared against a conversion curve which you use to work out the rebound value of the material.

The DRC Geo-Hammer mechanical rock test hammer is supplied with a carrying case, a conversion chart aoperating, and a calibration certificate. Each set also includes the following accesories for the proper inspection of concrete structures, a arbrasion stone, 30 x 30 cm plastic grid, pencil and paper notes, and 250 ml phenolphthalien.
