Laboratory Vane Tester which provides a wide measuring range of the shear stress. 

Features:

• Fully automatic controlled laboratory vane tester including complete data acquisition and evaluation system
• Determination of the shear strength of un-drained soft to stiff soils
• Test runs are completely reproducible
• Electronic control system with digital display and foil-keyboard for semi-automatic use by integrated control panel or fully automatic by PC with operating system Windows, control and evaluating software C 2090 W/32
• Highly precise stepless and load-independent control of the shear rate
• Automatic recording of the shear resistance (torque) against the displacement (angle)
• Unlimited shear displacement and automatic speed alternation according to default parameter (angle, failure or time), in order to observe the influence of the pore water pressure on drained and un-drained samples
• Input of the vane size leads to automatic shear force conversion
• Continuous on screen observation of the shear resistance in a force-displacement diagram
• Complete data evaluation and print out with diagram on every commercial printer
• All standard vanes are applicable (special sizes available)
