ES-2 Electrical Conductivity and Temperature Sensor

ES-2 Sensor

  • Sustained EC measurements in a pipe or tank
  • Direct measurements of pore water EC when used with the Wetting Front Fullstop
  • Check your EC values at any location with an internet connection

Complete the electrical conductivity picture.

The ES-2 Electrical Conductivity Sensor is engineered to measure the electrical conductivity of water in a pipe or tank. When you pair the new ES-2 with a GS3 or 5TE in the soil, you’ll begin to see a complete picture of the salts that are going through your system as well as the salts staying in your soil or substrate.

The ES-2 Electrical Conductivity Sensor is designed to measure the electrical conductivity in pipe water or tank water

The ES-2 measures temperature using an onboard thermistor, and electrical conductivity using a stainless steel electrode array.
