Used to determine the strength values of a rock specimen both in the field and in the laboratory.

They consist of a load frame for applying loads, on which a manual hydraulic jack is mounted. 

The applied load is measured by a high precision electric load cell with a digital display unit range 0-56kN proving: 65.000 divisions, 0.001 kN resolution, linearity 0.05%, hysteresis 0.03%, repeatability 0.02%

Core specimens up to 4" (101.6 mm). Easy reading of the distance between the conical points thanks to a graduated scale.
