Hand-Held Field Vane Shear Tester

The Vane Shear Tester takes direct readings of shear strength to depths up to 3 meters (10 ft). Three vane sizes allow for the direct determination of undrained shear strength of soft to stiff clays.

• The peak vane value is determined by a calibrated scale ring built into the head assembly.
• The cross handle is used both to push the vane to the desired test depth and apply the shearing torque.

To correct for the skin friction of the extension rods, a dummy probe replaces the vane and a skin friction test is per formed adjacent to the vane test location.
