Used to determine the strength values of a rock specimen, both in the field and in the laboratory.
The Digital Point Load Tester consists of a load frame for applying loads up to 55kN, on which a manual hydraulic jack is mounted. The tester accepts core specimens up to 101.6mm (4) in diameter.
The load is applied by two point load platens and a graduated scale indicates the distance between the conical points. Applied load is measured by a pressure transducer and shown on a digital display unit.
The strength index (Is
) is determined from the formula P/D²
is the force required to cause the failure and D
is the distance between the points at the moment of failure.
Supplied complete with wooden carrying case and goggles.
Approximate Dimensions: 400mm x 530mm x 720mm
