  • Description

    The simplest method

    Evacuate your sampling bottle down to approximately 50 kPa.  If the soil water tension is lower than 50 kPa, soil water solution will be extracted until vacuum and soil water tension are equalized.  When the samples are collected, the bottle is evacuated again.

    This portable vacuum has a rugged case and uses a powerful pump and rechargeable battery, which make it easy to collect pore water samples at remote locations.

    Applications

    • Qualitative analysis of soil water

    Benefits

    • Low cost
    • Easy handling

    Limits

    • Discontinuous sampling
    • Undefined sampling

VS-Single/VS-Twin Tensiometer-Controlled Vacuum Systems

  • Get Pricing
  • Picture

  • Description

    The VS series of vacuum systems from METER are capable of applying a constant or tension-controlled vacuum for long-term monitoring projects.

    The constant vacuum method

    The constant vacuum method is continuously maintained by a regulated vacuum pump. The vacuum can be set between atmospheric pressure and 85 kPa.

    Tension-controlled extraction

    A tensiometer measures the soil water tension.  The programmable vacuum station VS automatically supplies a vacuum in correspondence to the measured tension.  Due to the numerous functions of the unit, an optimal adaptation to the sampling task is possible.

    Applications

    • Long term monitoring projects
    • Studies on leachate under defined conditions
    • Soil water extraction from a certain pore size with a vacuum which is exactly suitable to the pore size
    • Lysimeter sites

    Benefits

    • High accuracy vacuum pump
    • Two vacuum outlets
    • Selectable constant or tension controlled vacuum
    • Optimized for use with rechargeable batteries
    • Input for one tensiometer: T8, T4, or T5
    • Multiple configuration options
    • Integrated data logger

    Limits

    • Configurable only by PC or laptop
