G3 wick lysimeter

The Decagon/METER Group G3 Drain Gage is a wick lysimeter for the accurate measurement of near surface drainage in the vadose zone. The G3 Drain Gage is typically installed beneath the root zone for drainage measurements but it can also be installed in other locations. Therefore, the G3 wick lysimeter is not only ideal for hydrology studies, but it can also be used for nutrient leaching studies.

Advantages of the G3 Drain Gage wick lysimeter include:

• Manual or automated measurements
• Connect to data loggers with remote download and alarms
• Simultaneous measurements of drainage, temperature and electrical conductivity (EC)
• EC measurements can be used to estimate soil nutrient leaching

 

further information

Use the Drain Gauge to determine the volume of water and chemicals draining from the vadose zone into groundwater. Once installed, water samples are easily collected through the surface port for analysis of chemicals, fertilizers, and other contaminants. The Drain Gauge is constructed from inert materials and will not react with compounds collected in the sample reservoir.

One challenge with is that water can flow around receptacles buried in the ground. To correct for this, our Drain Gauge uses an ingenious duct and wick design to keep soil tension in the soil column similar to that of the natural soil at the installation site.

customize your drain gauge

Choose from a stainless steel or PVC divergence tube. Stainless steel is recommended for taking an intact soil monolith, but is not recommended for heavy metal testing.

For most applications we recommend using the additional to measure conductivity, temperature, depth, and to help determine when to empty the sample reservoir. For installation sites that are remote or have high drainage rates, we recommend using the AutoPump to take samples or empty the reservoir automatically. The sensor and AutoPump can be easily integrated with pre-installed units and are ideal for use with a cellular data logger.

benefits

• Completely sealed system protects from high water tables
• 61 mm drainage capacity allows for large sampling volumes
• Can be used with the optional EC sensor to monitor solute fluxes
• Can be used with the optional AutoPump to automatically draw samples on remote or high drainage deployments

advanced data collection and management solutions

Edaphic Scientific recognises the need for flexible and adaptable sensor and data logging solutions for experimental or environmental monitoring projects.

Data can be downloaded directly in the field from data loggers. A direct connection between the data loggers and your computer, via a USB cable, can be used for manual downloading of data.

Alternatively, data can be downloaded over the internet on your iPhone, iPad or desktop computer with the Eagle.io cloud-based, data management software solutions. Through this remote based downloading capabilities, you can download, view and manage your data, and system, anywhere in the world and at anytime.
