Main Features

The laboratory Vane Shear Apparatus measures the shear strength of cohesive soils and is particularly useful for soils with low shear strength. Vane shear testing is a fast and economical method of measuring the shear strength of clay compared with elaborate tri-axial shear or direct shear tests.
This apparatus tests undrained strength of soils, both in undisturbed and remoulded conditions.
  • EASY PRELIMINARY TEST: a rapid method of determining soft soil shear strength, when an immediate value is required.
  • READY TO USE: Supplied with a 12.7 x 12.7mm Standard Vane and set of four calibrated springs.
  • EASY TO UPGRADE: Simple upgrade from manual to motorized versions.
  • ALTERNATIVE CONFIGURATIONS: Supplied with a 200mm base plate for standard specimen molds and sample containers. The optional attachment will also firmly hold sample tubes up to 100 mm, sample jars or a special container.
