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 analogue signal means no-hassle integration with
systems manufactured by other companies.
Cover more space
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.
