Drain Gauge

Gee Passive Capillary Lysimeter

The Drain Gauge allows you to measure the flux of water and solutes through the soil profile. It sits below the root zone, collecting down-welling water into a duct and wick system. The collected water volume is recorded by a surface data logger. A surface port allows you to draw out samples to analyze for chemicals, fertilizers, and other contaminants.

With a galvanized steel exterior and no moving parts, the Drain Gauge is ideal for long-term underground use--no need to dig it up for maintenance and inspection. The collected water is stored in an inert receptacle until it is extracted.

Compatible with Em50 and CSI dataloggers (will not work with the Em5b).
