Benefits of using Equi-pf to determine the soil moisture release curve:
- Fully automated – the sample is put in place and no further operator intervention is required.
- No disturbance of the sample during tests.
- Programmable tension steps.
- Soil reaches equilibrium at each tension step.
- Each tension step has a user settable time limit to reach equilibrium.
- Weighing errors are eliminated – inflow and outflow water volume is measured directly, to an accuracy of 0.1 ml.
- Outflow and inflow curves, both cumulative and for the current tension are automatically updated and displayed on a graphical LCD.
- Each tension step can be manually bypassed.
- Allows multiple continuous drying and wetting cycles.
- Data on hysteresis in soils.
