The GS1 is a ruggedized version of our basic, no-frills soil moisture sensor. It accurately measures volumetric water content in soil or soilless media.The longer lifetime of the GS1 helps your budget go further.
It delivers research-grade accuracy at a price that makes large sensor networks economically practical. Characterize your site with sensors at multiple depths and locations, even on a tight budget.
Epoxy body withstands tough field conditions
This sensor is built to last longer in the field under warmer, wetter conditions. The epoxy body withstands harsh environments and water intrusion.
Stainless steel needles for easy installation
Two stainless steel needles cut through the soil for better soil-sensor contact and easier installation. Needles are also much more durable than our standard sensor blades.
Full VWC range & large volume of influence
The GS1 is sensitive across the entire water content range. It can be installed in dry desert soils or in very wet peat. Sensitive to small changes in water content anywhere from 0 - 100% VWC. Plus, it has one of the largest volumes of influence on the market-690 cm³.
70 MHz frequency capacitance technology
This frequency minimizes salinity and textural effects, making the GS1 accurate in most soil or soilless media. Can be used in a variety of conditions with the factory calibration.
