T4 Tensiometer
The T4 precision Tensiometer - developed for outdoor monitoring projects. Only the ceramic cup is filled with water for highest accuracy and year-round operation.
Optionally with external refilling:
The model T4e with external refilling can be refilled or emptied without removing it from the soil.
Typical Applications
- Field measurements
- Water balance, leaching, transport studies, model calibration
- Ecological impact studies
- Agricultural or forestal studies
- In-situ retention curves
- Data logger applications
- Spot readings in with the INFIELD7
Advantages
- Reliable outdoor tensiometer
- Solid construction
- Year-round operation when installed deeper than 30 cm
Limitations
- Not for dry soils
- Installation ancle between 20° and 70°. At vertical and horizontal installation an air bubble will remain in the cup.
