Company Profile

Usage:

The Miniature Soil Lysimeter System is a set of devices designed to directly measure evapotranspiration based on the water balance principle. It enables precise measurement of rainfall, evapotranspiration, and drainage. The system can be equipped with various types of sensors to meet scientific research needs in the fields of water balance, material balance, and soil solute transport.

Features:

Compact size and lightweight design, making it easy to transport and install for rapid deployment.
Economical and cost-effective, with the ability to be configured in groups to reduce experimental errors.
Made of durable, non-polluting materials to minimize measurement errors caused by rust and corrosion.
Direct measurement of water balance.
Automatic drainage system.
Automatic remote data transmission to the cloud platform.
Powered by solar panels and batteries for unattended operation.
Optional accessories include rain gauge, tensiometer, soil moisture sensor, soil conductivity sensor, soil temperature sensor, and remote data transmission module.
Customizable for sloped land applications according to customer requirements.
