Vane Test

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 100Omm 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.
