  • Moisture Content, Bulk Density, and Total Porosity
  • 5-7 Point Soil Water Characteristic Curve, Wetting or Drying
  • Curve fitting using both the van Genuchten and Brooks-Corey methods

TRI also has the ability to add additional points to SWCC using:
  • Hanging Column Method, Triaxial Pressure Plate, Chilled Mirror Hygrometer, Filter Paper, and Relative Humidity Box
  • Rapid Determination of residual moisture content
  • 5-7 Point Soil Water Characteristic Curve, Wetting or Drying
  • Matric Suction Potential using Filter Paper Method
