The Rock Classification Hammer is a portable, spring-loaded impact device used to evaluate the surface hardness of rock specimens by measuring rebound values.
The hammer is applied perpendicularly to the surface of horizontally positioned rock cores, typically of NX or NW size, to obtain rebound readings.
Multiple measurements are taken along the length of the core to calculate an average rebound number, providing a rapid and non-destructive assessment of rock hardness.
This method is particularly useful for preliminary site investigations, rock mass classification, and quality control in both field and laboratory settings.
The device is supplied with a carrying case for ease of transport. A rock cradle, which facilitates consistent positioning during testing, is available separately.
