Dependable deep drainage measurements within your budget.

Meet the Drain Gauge G3 Lysimeter. Finally, there’s a dependable way to monitor leaching, drainage, and recharge without the complexity and cost of a larger system. The Drain Gauge G3 is a passive-capillary lysimeter that determines the volume of water and chemicals draining from the root zone into groundwater. Once installed below the root zone, water samples are easily collected through the surface port for analysis of chemicals, fertilizers, and other contaminants.
