Description
Especially designed to measure the undrained shear strength (CU) of cohesive soils, consists of a cylindrical body with a torsional spring and three interchangeable vanes of different sizes used depending upon the expected strength of the soil. The height/diameter ratio of all vanes is 2. During operation the vane is driven for 5-6 cm into the soil and then turned with the handle. Deep measures (i.e. on the top of undisturbed samples) can be obtained using the extension rod.
All stainless steel construction. Supplied in a plastic case.
Note: This unit is also part of the Field inspection testing kit which also include the 16-T0163 penetrometer described in Pocket penetrometers.
