Standards: ASTM D5731, ISRM
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, 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 0-56 kN proving:
- 65.000 division
- 0.001 kN resolution
- Linearity: 0.05%
- Repeatability: 0.02%
- Hysteresis: 0.03%
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.
Supplied complete with wooden carrying case, goggles, accessories.
High precision electric load cell.
Capacity 56 kN.
Core specimens up to 4" (101.6 mm).
Easy reading of the distance between the conical points thanks to a graduated scale.
Dimensions: 400x530x720 mm
Weight: 25 kg approx.
