Decagon ES-2

Irrigation EC Sensor– salinity & temperature sensor

  • Continuous EC measurements in a pipe or tank
  • Ideal for irrigation nutrient monitoring
  • Check your EC values anywhere with an internet connection

The ES-2 Electrical Conductivity Sensor is designed to measure the electrical conductivity of water in a pipe or tank.  When you pair the new ES-2 with a GS3 in the soil, you’ll begin to develop a complete picture of the salts that are going into your system as well as the salts remaining in your soil or substrate.
