Soil Tensiometer

Product Description

Soil Tensiometer

The Soil Tensiometer is a simple, robust, and cost-effective device used to directly measure soil water tension, enabling accurate monitoring of soil moisture levels. Essential for agronomy, irrigation management, and research applications, this tensiometer helps users understand plant water availability and optimize irrigation practices.

Key Features

• Direct Soil Moisture Measurement: Provides a real-time reading of soil suction, indicating how tightly water is held in the soil and how available it is to plants.
• Modular Design: Easily replaceable ceramic tip and vacuum dial gauge, available in various lengths from 15 cm (6") to 150 cm (60") to suit shallow and deep root zones.
• Vacuum Gauge Range: Measures up to 85 centibars, the practical limit before cavitation occurs.
• Optional Jet-Fill Reservoir: Facilitates easy filling and maintenance; includes a reservoir button for air removal without a vacuum pump.
• Clear Assembly and Use: Includes step-by-step setup, installation, and maintenance guidelines.
• High Accuracy: Factory-sealed and adjustable dial gauge ensures zero reference accuracy even at high altitudes.

How It Works

The porous ceramic tip of the tensiometer maintains hydraulic contact with the soil. Water flows into or out of the tube depending on soil moisture levels. The vacuum gauge equilibrates with the soil tension, giving a direct reading on how much effort roots must exert to access water.

Applications

• Agricultural irrigation scheduling
• Greenhouse and nursery management
• Research in soil and plant sciences
• Monitoring soil moisture in orchards and vineyards
• Water conservation initiatives

Available Lengths

• 6", 12", 18", 24", 36", 48", and 60" (15 cm to 150 cm)

Precautions

• Avoid use in freezing temperatureswater inside may freeze and damage components.
• Ensure good soil contact with the ceramic tip for accurate readings.
• Regular air removal and refilling improve accuracy and reliability.
