Our Easy-To-Go Lysimeter (ETG) complements our product range for field lysimeters in the low-cost range. It offers a standardized alternative to our flexibly equipped Ready-To-Go lysimeters and still provides all the essential functions for determining the most important soil water balance parameters. The ETG comprises a lysimeter vessel with a diameter of 300 mm and a height of 600 mm as well as two soil moisture and soil temperature sensors (SMT-100), a tipping counter, a weighing system and a mast with data logger.

In the Plus version, two FRT-SMs are installed instead of the two SMT-100s, so you can also measure the tension.

The data is continuously transmitted to your individual SVADSS data management portal via NB-IoT wireless technology. All ETGs are suitable for both disturbed (manual filling) and undisturbed soil monoliths (special sampling technology). The ETG lysimeter station can be set up and put into operation without special tools and even without trained UGT personnel.

Precise water balancing directly on site

In conjunction with an NB-IoT weather station, the cost-effective ETG enables precise quantification of the local water balance. You can determine evapotranspiration directly and reliably via the change in weight of the lysimeter. With our highly specialized weighing system, you benefit from our wealth of experience in the field of lysimeter technology. This precise technology enables direct water balance analyses with a resolution of 0.01 mm. The detection of dew, snow and small amounts of evapotranspiration is no problem.

Insights into the “black box” of soil

In addition to weighing, our ETG lysimeters are equipped with high-resolution soil moisture and soil temperature probes (SMT-100). Soil moisture is measured in volume % water content and is an important parameter in the water balance of the soil monolith. In addition, the free outlet at the bottom of the monolith and the automatic submersible pump at the bottom of the outer vessel enable quantitative and qualitative investigations of the seepage water.

High spatial repeatability for comprehensive investigations

With the affordable design of the ETG lysimeter, you can measure water balance variables directly or set up a dense lysimeter network, even on a limited budget. This gives you a high spatial resolution for researching the landscape water balance or for assessing water management issues.

Note: Automatic data transmission using NB-IoT requires good network coverage.
