Product description: A reasonable assessment of water balance and evapotranspiration is an important part of hydrological cycle; a lysimeter is a useful tool to evaluate the use of water in the soil, water storage and transfer in the same location. QT-3051 series lysimeter can apply to laboratory for the study on parameters relevant to water balance.
QT-3051 series Micro soil lysimeter
To make calculation easy, the height of column barrel of this system is designed to 300 mm, 600 mm, 1200 mm respectively, other height can be customized. The system uses state-of-the-art high-resolution weighing system, high-precision soil moisture and water potential sensor to ensure the accurate measurement of the entire system.
Applications
The lysimeter system can be used in many area, such as water characteristic curve, ecological restoration, small-scale simulation experiment, fluidity of soil water, soil mass transfer, soil absorption and buffering, water balance analysis, leachate analysis, groundwater recharge analysis, mass migration, material transformation research, farming method research, climate research, energy balance studies, correction of simulation experiment, water flux studies, simulation studies on groundwater recharge, determination of the leachate and so on.
