Rock classification hammer

Used to measure the rebound index on rock cores and samples. It is similar to the one used for testing concrete, but has a different level of impact energy: 0.74 Nm. Rock cores are positioned horizontally and the rebound index is obtained from the average of several measurements performed perpendicularly to the longitudinal axis.

Impact energy: 0,74 Nm
Measuring range: 10…60 N/mm2
Weight: 2 Kg
