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.
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.
