產品介紹
The VS-pro series of vacuum systems from UMS are capable of applying a constant or tension-controlled vacuum for long-term monitoring projects. Keyboard display allows for status checks and configuration without hooking it up to your PC.
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
Defined pore water sampling
Defined leachate measurements
Lysimeter sites
Tension controlled sampling
