Digital Point Load Tester Description and Specifications for Lab Tenders
Digital Point Load Tester.
Used to determine the strength values of a rock specimen both in the field and in the laboratory. It consists of a load frame for applying loads up to 55 KN, on which a manual hydraulic jack is mounted. The instrument accepts core specimens up to 4″(101,6 mm) diameter which are loaded by two coneshaped points. A graduated scale indicates the distance between the conical points. The applied load is measured by a pressure transducer with a digital display unit range 0â€56kN, 65.000 divisions, 0,001 kN resolution, accuracy: ± 1%. The strength index (IS) is got by the formula P : D2 where P is the strength and D the space between the two conical points.
