    • Determination of the retention curve hysteresis (wetting – drying cycle) in porous media.

    Examples of use:

    • Dynamics of soil water potential – soil moisture dependence.
    • Determination of  characteristic points on water retention curve characterizing of soil water availability for plants.

    • Measurement of porous media moisture within the range from 0 to complete saturation.
    • Measurement of soil water potential from -800 hPa to 0.
    • Measurement of electric conductivity from 0 to 1 S/m.

    Examples of use:

    • Measurement and monitoring of changes in soil moisture and soil water potential.
    • Determination of the water retention curve and water conductivity with the instantaneous profile method
    • Monitoring of moisture, electric conductivity and temperature of soils and other porous media
