Standard: ASTM D2573
The Field Inspection Pocket Vane Tester is especially designed to measure the in situ undrained shear strength in clays. The instrument consists of a T-handle cylindrical body where a torsional spring in housed, and three interchangeable vanes of different sizes, used depending to the expected strength of the soil to be tested. 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.
Feature
*Perfect kit for all those measuring in top soils.
*Ideal for agronomists, civil engineers.
*Small but sensitive and accurate.
*Drag ring for easy read-out.
*Dummy used for zero measurement.
