System Introduction
Reasonable assessment of water balance and evapotranspiration is an important link in the hydrological cycle, and lysimetry system is a brand-new tool for assessing the utilization of water in soil; the storage and transfer of water in the same location. The micro lysimetry system is specially used to study the long-term monitoring of the hydrological cycle of the ecosystem. With the continuous in-depth development of soil physics, meteorology and other fields, it can be used for research on landfill, soil pollution, groundwater pollution and other related aspects.
The material of the soil column bucket is stainless steel, and the size can be customized according to the needs. For small soil column research, the recommended size is 30-60cm in diameter and 30-100cm in height (other sizes can be customized according to customer needs). soil or backfill for monitoring.
Measurement Parameters:
Soil moisture, soil temperature, soil evaporation, soil infiltration
Optional measurement parameters: soil conductivity, soil heat flux, soil water potential, soil solution sampling
System Features
It can display data in real time and receive data regularly.
Send data in real time and download data automatically and regularly, without the need for personnel to collect data.
The output data is in tabular format, which is easy to be called under Excel and various data processing software and database software
