TR-0563 The type L Original Schmidt is the ideal option for testing thin walled items with a thickness between 50 to 100 mm (2“ and 4”) or for analysing small components. It is also suitable for examining cast stone components which are sensitive to impact. In rock mechanics, the type L Original Schmidt is commonly used for the classification of rock cores and brittle rock.
TR-0563 Type L Hammer is a portable and relatively inexpensive İnstrument for measuring the surface hardness of rock. The hammer can be used efficiently in both the laboratory and the field.
The mechanism of operation is simple: a hammer released by a spring, indirectly impacts against the rock surface through a plunger and the rebound distance of the hammer is then read directly from the scale ranging from 10 to 70 MPa (1,450 to 10,152 psi).
The type L hammer is used on NX or larger core specimens or block specimens having an edge length of at least 6 cm. TC-3040 Calibration Anvil, manufactured from a special steel alloy, is used for the calibration of test hammers.
