Features
- Test results are saved and displayed in real-time, speeding data capture.
- Results are then processed using Wykeham Farrance (WF)’s easy-to-use Geo-Analysis templates, written by experts around international standards allowing you to concentrate on analysing your materials; not on programming your testing machine.
- 40 cm 2 stainless steel ring shear box fitted with easily removable sintered porous stone.
- Sintered porous stone with special pattern design guarantees torsional shear force application.
- Conforms to Test Standard ASTM D6467 | BS 1377:7
- Fully automatic standalone ring shear soil testing system for performing torsional ring shear test in drained condition to determine the residual shear strength of cohesive soil.
- Managed by local user interface with 6” touch screen high resolution colour display
- Environmentally friendly and quiet with brand new Electromechanical Servoactuation (EmS) technology
