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 soil-less media. Factory calibrations are included for mineral soils, potting soils, rockwool, and perlite.
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.

Reasons to pick the EC-5
Volumetric water content is the only measurement you need
Simple sensor with excellent accuracy
Small volume of influence (eg., field spatial variability, lab column studies, or greenhouse research)
