Model EC-5 - Soil Moisture, Small Area Of Influence



Our lowest-cost soil moisture sensor. Measures Volumetric Water Content only. Just 5 cm long with a 0.3 L measurement volume, this handy little sensor is easy to install in the field and can also be used in nursery pots.


Lowest Cost Individual Sensors for Large Sensor Networks

Looking for a basic, no-frills soil moisture sensor? Use the EC-5 to accurately measure water content in any soil or soil-less media with minimal salinity and textural effects.

The EC-5 delivers research-grade accuracy at a price that makes large sensor networks economically practical. You can adequately characterize your site with 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. The sensor uses a 70 MHz frequency, which minimizes salinity and textural effects, making the EC-5 accurate in almost any soil or soil-less media. Factory calibrations are included for mineral soils, potting soils, rockwool, and perlite.

Easy Installation

The EC5’s small size makes it easy to install--handy in field installations and good for nursery pots. The EC-5's robust design makes it easy to push directly into undisturbed soil to ensure good accuracy.

Integrate with CSI Data Loggers

The EC-5's analog signal means no-hassle integration with systems run by other data loggers (like CSI).

Reasons to pick the EC-5:

  • If volumetric water content is the only measurement you need.
  • If you have a tight budget
  • If you just want a simple, all-purpose sensor with excellent accuracy.
  • If you are interested in a small volume of influence (eg., field spatial variability, lab column studies, or greenhouse research).


Auger Kit

For use with deep installation of the ECH2O probes. Includes a regular and sand auger (2.75' [7 cm] diameter), two 2' (0.6 m) extension rods, a standard rubber handle, and a ratchet handle.


Cable Armor

Give your cables a higher level of protection from the elements and rodents. Also organizes your cables as you run them to your datalogger.


Splice Kit

Repair damaged cables in the field with few tools and less time.
