Product Summary:

The Soilspec Tensiometer System Computer V is an advanced soil moisture monitoring solution designed for accurate, real-time irrigation management. This system measures soil water tension, giving growers a direct understanding of how much effort plants exert to extract water from the soil.

Used by government agricultural departments, universities, and research institutions such as the CSIRO, the Soilspec Computer V offers reliable and precise readings for all crop types and soil conditions. It requires no calibration and features rugged components for long-term use in the field. The accompanying Moisture Plot software enables data download, visualisation, and interpretation of moisture trends across multiple depths and sites.

Soilspec Tensiometer Tubes

The Soilspec Tensiometer Tubes form the foundation of the Computer V Soil Moisture Monitoring System. These precision-engineered tubes are designed to provide a direct, physical measure of how difficult it is for plants to extract water from soil — a critical factor in irrigation management.

Each tube is constructed from clear acrylic or PVC and fitted with a high-flow porous ceramic tip at the base. The tube is filled with degassed water and sealed with a rubber stopper to maintain vacuum integrity. As soil dries, water is drawn from the ceramic tip, creating a measurable suction that correlates directly with soil water tension.

Two standard diameters are available — 20 mm and 40 mm — allowing flexibility for different crop types and soil structures. The 20 mm slim-line tube is ideal for minimal disturbance and permanent field installation, while the 40 mm model offers a greater internal volume, suitable for soil solution extraction and multi-point monitoring applications.

When installed at varying depths (commonly 30 cm, 60 cm, and 90 cm), Soilspec tubes reveal moisture movement throughout the root zone and support precise irrigation scheduling. Readings can be taken manually or recorded digitally via the Computer V gauge, then visualised using the Moisture Plot software.

Key Technical Details:

• Tube Material: Clear PVC or acrylic (UV-stabilised)
• Ceramic Tip: High-flow porous type (suitable for sandy to loamy soils)
• Typical Depths: 30–90 cm
• Measured Parameter: Soil water tension (centibars or kPa)
• Maintenance: Periodic refill with degassed water; keep ceramic tip saturated
• Integration: Compatible with Soilspec SST102G Computer Gauge and Moisture Plot software

Applications:

• Field and research monitoring for olives, grapes, citrus, and almonds
• Salinity and nutrient tracking through soil solution extraction
• Long-term irrigation management and environmental compliance

These tubes are used by CSIRO, NSW DPI, and SARDI in national research programs for their accuracy, ruggedness, and reliability in diverse soil conditions. Built for both research and commercial use, Soilspec tubes deliver consistent performance and require minimal maintenance over years of operation
