Hand Vane Tester

The Hand Vane Tester from TT Precision Engineering is a rugged, high-precision instrument designed specifically for the rapid determination of the undrained shear strength of cohesive soils. Whether used directly in the field during a geotechnical site investigation or on undisturbed samples within a laboratory environment, this tool provides essential data for engineers and soil technicians.

Its lightweight and portable design ensures that high-quality measurements can be taken in even the most challenging environments, providing an immediate assessment of soil stability and load-bearing capacity.

TT Precision Engineering provides a standard supply of spare parts for the vane tester, including a 19mm vane, a 33mm vane, a 1000mm extension rod, and various adapters.

• Exceptional Portability: Designed for field-readiness, the tester is easy to transport, making it an ideal companion for site surveys and remote geotechnical investigations.

• Versatile Testing Capabilities: Perform measurements in-situ on the ground surface or on samples in the lab to ensure data consistency across all project phases.

• Durable Engineering: Manufactured by TT Precision to withstand the rigours of construction sites and environmental drilling.

• Extended Reach: Compatible with 1000mm extension rods, allowing for deeper profile assessments without the need for large-scale drilling equipment.

Technical Specifications & Accessories

To ensure accuracy across various soil types—from soft clays to stiffer silts—we provide a comprehensive range of interchangeable vanes and accessories:

• Standard Vanes: Includes both 19mm and 33mm vanes to accommodate different soil consistencies and strength ranges.

• Extension Rods: 1000mm high-grade steel extension rods for vertical profile testing.

• Precision Adapters: A variety of adapters to ensure secure connections and minimized friction during torque application.

• Replacement Parts: We maintain a full stock of spare parts to ensure your equipment remains in peak operational condition with minimal downtime.

How the Hand Vane Tester Works

The Hand Vane Tester operates by inserting a four-bladed vane into the soil and applying a torque. The maximum torque required to shear the soil is measured, which is then converted into a shear strength value. This method is a globally recognized standard for analyzing saturated, cohesive soils where undrained conditions are a primary concern for structural safety.

Typical Applications

The TT Precision Hand Vane Tester is widely used across several industries, including:

• Geotechnical Engineering: Fundamental site investigations for building foundations and earthworks.

• Civil Engineering: Assessing the stability of embankments, slopes, and trenches.

• Agriculture & Soil Science: Researching soil compaction and structural integrity.

• Coastal & Marine Surveys: Analyzing soft sediment strength in tidal or marshland environments.
