ECH20 EC-5
Soil Moisture Sensor
The EC-5 delivers research-grade accuracy at a price that makes large sensor networks economically practical. You can adequately characterize your site with soil moisture sensors at multiple depths and locations, even if you’re on a tight budget.
Engineered for accuracy
The EC-5 determines volumetric water content (VWC) by measuring the dielectric constant of the media using capacitance/frequency domain technology. Its 70 MHz frequency minimizes salinity and textural effects, making this sensor accurate in almost any soil or soilless media. Factory calibrations are included for mineral soils, potting soils, rockwool, and perlite.

Easy installation
Just 5 cm long with a ~0.2 L measurement volume, this handy little sensor is easy to install in the field and can also be used in nursery pots. The EC-5’s compact design makes it easy to push directly into undisturbed soil to ensure good accuracy.
Easy integration
The EC-5’s analog signal means no-hassle integration with systems manufactured by other companies.
