Overview:
DJ-2104 Compact Soil Lysimeter System is a group of equipment that directly measures surface evapotranspiration based on the principle of water balance, and can accurately measure rainfall, evapotranspiration and drainage; it can be equipped with various types of sensors and can be used to study water balance, material balance, Research in the field of soil solute flow.
Benefits and Features:
Small area requirement, light in weight; easy to transport and install, and can be deployed quickly.
Lower cost and less experimental errors.
Long life time and non-polluting materials, less measurement errors caused by material rust and structural corrosion.
Directly measure the water balance.
Solar panel with battery power supply can be operated automatically.
Optional rain sensor, tensiometer, soil moisture sensor, soil conductivity, soil temperature sensor, data remote transmission module, etc.
According to customer requirement, we can customize small soil lysimeter systems for slopes.
