The M-1000 vane borer is an instrument for carrying out in-situ shear tests in cohesive soils. The test results appear graphically on a waxed paper disk that constitutes a permanent record. It is simple to use and has a very small relative vane volume displacement.
The instrument is normally mounted on a boring rig for testing at various depths without a drilled hole, or is mounted on the casing of a borehole using an adapter.
