Scientific equipment for climate research, industrial measurements and air quality analysis

UGT LYSIMETERS


Delineated soil columns with a known volume and surface area for laboratory or field use to determine water balance variables.

UGT has continuously developed lysimeter technology for 25 years. Their patents, which cover both the station itself and the sensors in the lysimeter, enable scientists in Europe and around the world to carry out their lysimeter experiments using state-of-the-art technology. Customized versions will be implemented on request.
Weighable and nonweighable lysimeters can be equipped with leachate collecting system, additional sensors (such as tensiometers, soil moisture probes, thermometers, and suction probes), pore water extraction system, UGT weather station with climate sensors and module for controlling the lower boundary condition of the Lysimeter.

  • utilize to investigate water balances of ecosystems or crop water use of rain fed crops
  • add sensors such as tensiometers, soil moisture probes, thermometers to investigate functioning and mechanisms of ecosystems 
  • typically used at agricultural sites, forest sites, landfill sites and post-mine landscapes
  • up to 4 lysimeters can be put together in autonomous UGT-lysimeter stations made of PE-HD
  • non-destructive excavation of the soil monolith by patented UGT-Excavation Technology

 

UGT lysimeter


UGT large customized lysimeter

Lysimeter can be build from solid concrete or hermetically sealed PE-HD container stations. In special cases, the possibility exists to integrate metal housing (usually stainless steel). 
Different versions are available:
  • weighable and non-weighable lysimeters
  • forest lysimeters
  • groundwater lysimeters
  • hillside lysimeters
  • moor lysimeters
  • roof lysimeters
  • urban track lysimeters
  • applications: agriculture & soil science
