Precision Lysimeter for Contaminant Tracking in Soil Profiles
A lysimeter is a scientific instrument usually in a shape of a large soil container with a known volume and surface area. It is used to measure the amount of water that percolates through a soil column with a known volume and surface area and to analyze the movement of nutrients, salts, irrigation affects, or contaminants in the soil profile.
The EcoLab flex is a new generation of ecotrons where the optimal technical support to answer your research questions is our goal. The EcoLab flex can be designed e.g. as a single ecotron with one lysimeter, as a single ecotron with several stackable lysimeters or as a double station.
The Easy-To-Go Lysimeter (ETG) is a cost-effective lysimeter solution. It provides all the essential features for determining the key components of soil water balance.
The ETG consists of a lysimeter vessel with a diameter of 300 mm and a height of 600 mm, along with two soil moisture and temperature sensors, a tipping counter, a weighing system, and a data logger enclosure. The data is transmitted wirelessly to a data management portal. All ETG units are suitable for both constructed and undisturbed soil monoliths (using specialized sampling technology). The ETG lysimeter station can be set up and operated with standard tools—no training is required.
The Lab Lysimeter is a small weighing lysimeter lab setup suitable for both Constructed and Undisturbed soil monoliths. The Lab Lysimeter has applications in the water budget and ET studies.
The Soil Column setup is similar to the Lab Lysimeter. The Soil Column setup does not have a weighting feature, and it is suitable for soil hydrology and chemical transport modeling.
There are several options of diameter (200 to 800 mm) and height (200 to 1,500 mm).
- Energy efficient chiller
- One lighting level
- Accommodation of 6 small lysimeters
- Two thermally isolated climatic areas
- 12″ touch panel
The poly klima® growth cabinet M1 was developed for plant biological applications that require stable and consistent ambient conditions. It has two climate areas with a horizontal insulation level. In the upper atmosphere area you control the temperature, humidity and CO2 concentration. In the partition between the climatic zones there are openings for 6 small lysimeters, which we as UGT can offer you as a complete solution. The temperature in this lower area can be set independently and is used to regulate the lysimeters.
Small size with a lot of measurement technology
To complement the product line, UGT has developed a smaller and more cost-effective solution for field studies in addition to the large PE-HD lysimeter stations. The Ready-To-Go Lysimeters are small weighable lysimeter stations suitable for monoliths with a diameter of 300, 500, 800 or 1130 mm and a length of 300, 600 or 900 mm. All Ready-To-Go Lysimeters (RTG) are suitable for both disturbed (filling by hand) and undisturbed soil monoliths (special sampling technique). The entire RTG lysimeter station can be set up and put into operation without special tools and also without trained UGT personnel. The standard RTG system consists of a stainless steel lysimeter vessel, a weighing system, a leachate tank with tipping trough, a set of high-precision and accurate-fitting soil hydrological sensors, and a control station for each. With UGT sensors such as tensiometers, water content and temperature probes, and suction probes, we can help you study ecosystem function and effects. The RTG system can be extended by a pore water harvesting system and the UGT weather station module with climate sensors.
