The Geo Site Supply Hand Vane Tester is a precision field instrument for measuring the undrained shear strength of soft to firm cohesive soils directly in the ground or in trial pit exposures. An essential piece of equipment for geotechnical site investigation, it provides reliable shear strength data without the need for laboratory testing.
How it works
Four thin vanes are pushed into the soil and slowly rotated. The torque required to shear the soil is measured by a calibrated spring mechanism, providing a direct reading of undrained shear strength (Su) in kPa or kN/m². Both peak and remoulded strength can be measured, allowing calculation of soil sensitivity.
Key features
- Measures undrained shear strength in kPa or kN/m²
- Interchangeable vane sizes for different soil strengths
- Peak and remoulded strength measurement
- Robust carrying case protecting the instrument
- Calibrated spring mechanism for accurate readings
- Suitable for soft clays, silts, and cohesive fills
Typical applications
- In-situ shear strength profiling during site investigation
- Bearing capacity assessment for shallow foundations
- Stability analysis for embankments and cuttings
- Correlation with lab test results for BS 5930 reporting
Hand vane tester vs pocket penetrometer
The hand vane tester measures undrained shear strength directly in kPa, making it more accurate and quantitative than the pocket penetrometer, which estimates unconfined compressive strength. For projects requiring precise shear strength values for design, the hand vane tester is the preferred instrument.
