This lightweight and portable impact hammer is used for rock classification tests.
The hammer is similar to a device used for many years for strength classification tests of mass concrete. Cylindrical cores, usually NW size, are held in a horizontal position and the hammer mechanism impacted against the core to obtain rebound readings. A series of readings is taken along the length of the core to get the average rebound number.
