The Hand Vane Tester is 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. The instrument comprises a torque head with a
direct reading scale which is turned by hand. A non-retum
pointer indicates the reading. Vanes either 10mm or 33mm
diameter, with optional extension rods are screwed into the rear
of the torque head, and pushed at least 20Omm into undisturbed
clay. Extra 300mm or 1000mm extension rods can be used for
greater penetration and for gaining access to difficult or
dangerous locations. The unit shows on the dial a conversion
factor to BS 1377 Vane Test results.
