Digital Point Load Tester with NATA Calibration - AF-RM-120

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 50kN, 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 where P is the force required to cause the failure and D is the distance between the points at the moment of failure.
