Decagon - EC-5 Volumetric Water Content Sensor
SKU: MD-01070
PKR 14,500.00

Availability: Preorder, Delivery in 15-20 Days

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.
Description

Details

Low Cost Individual Sensors for Large Sensor Networks

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. 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.

Features

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