Lysimeter – Measuring Evapotranspiration

Lysimeters today are precision tools for environmental monitoring research projects like climate research, water management, agronomy, soil science or site remediation.
Our lysimeters monitor the hydraulic and thermal conditions of the surround-ing field. Their sophisticated measuring, sampling, controlling and regulating instrumentation monitors the real field situation.

Soil water is the decisive parameter for mass balance determination. For studies on groundwater recharge or mass transport or for metabolism research it is significantly important to have a field-identical water regime inside the Lysimeter.

For climate research or analysis of microbial activities our Lysimeters offer thermodynamic comparability between field and Lysimeter.

Whether your field of activity is soil science, climate research, water management, agricultural research or remediation of contaminated sites, our modern Lysimeters contribute the essential monitoring results. Today high-precision sensors are available that reveal the smallest amount of precipitation as dew and frost.

High-resolution data loggers store short-interval readings over extended periods of time to visualize details of ongoing processes, mass conversion or solute transport.

You can bring together data from numerous UMS Lysimeter sites, which then are available as a common and substantial data base for a research network.
