General Items
During triaxial and permeability testing, even very small volume changes can significantly influence soil behavior interpretation. The AZA0906 connects directly in-line with the drainage or back-pressure circuit of the triaxial system and records water movement using a precision-calibrated burette or piston mechanism. Its high resolution ensures that minute volume changes are captured accurately and repeatably throughout the test duration.This makes the AZA0906 indispensable for laboratories performing effective stress analysis, stress-path studies, and advanced soil research.
Applications
The AZA0906 Volume Change Gauge is widely used in:
- CU and CD triaxial shear tests
- Soil consolidation and swelling studies
- Permeability testing of cohesive soils
- Volumetric strain measurement under controlled drainage
- Academic research and commercial geotechnical laboratories
Measured data from the AZA0906 is used to determine key soil parameters such as volume compressibility, bulk modulus, coefficient of permeability, and dilation characteristics.
Construction & Features
- Precision borosilicate glass or acrylic burette (typically 50–100 ml)
- Clearly calibrated scale with ±0.1 ml resolution
- Smooth, low-friction plunger or piston mechanism
- Optional dial gauge or LVDT for displacement measurement
- Pressure-tight drainage and back-pressure connection ports
- Rigid metal frame with vertical mounting and leveling base
- Leak-proof design to prevent air entrapment and data errors
Optional digital upgrades allow integration with automated data acquisition systems for continuous logging and analysis.
Standards & Compliance
The AZA0906 is designed in accordance with major international soil testing standards:
- ASTM D4767 – Consolidated Undrained Triaxial Compression Test
- BS 1377 Part 7 – Effective Stress and Triaxial Tests
- IS 2720 (Part 11 & 12) – Triaxial and Consolidation Tests
Key Benefits
- High-precision measurement of soil volume change
- Suitable for manual and digital triaxial systems
- Stable, vibration-free mounting for consistent readings
- Essential for effective stress and volumetric behavior analysis
- Durable, corrosion-resistant construction for long-term use
