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.
