Pocket Shear Vane
Pocket shear vane is widely used for taking on-site measurements of excavations, including trenches and test pits to determine shear strength values of cohesive soils. It is also used for taking readings from thin-wall or split core soil samples.
The PSV can be used to gather a large number of readings including those from different failure planes without the need to prepare and trim samples. The device can be used on any reasonably flat surface that is slightly larger than the vane surface being used. It can also be used with fully-saturated, fine-grained soils with an undrained strength independent of normal pressure, including a wide range of clays from soft to stiff consistency.
Readings can be made from 0 to 2.5 TSF (1 Kg/cm2). The dial on the unit reads in 0.05 TSF (0.05 Kg/cm2) increments.
Can be used in the laboratory for evaluations. The device is widely used by safety and OSHA inspectors, back hoe operators, field testing technicians, consulting engineers, etc.
