Hand Vane Soil Tester

An accurate and portable instrument for the determination of in-situ shear strength of cohesive soils either on site or on undisturbed samples in the laboratory.

Comprises a torque head with a direct reading scale which is turned by hand.

A non-return pointer indicates the reading.

Vanes either 19mm or 33mm diameter with optional extension rods are screwed into the rear of the torque head and pushed at least 200mm into undisturbed clay (19mm x 215mm or 33mm x 235mm).

The unit has recently been adapted to show on the dial a conversion factor to B.S. 1377 Vane Test Results.
