Electrical Conductivity and Temperature Sensor

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 or 5TE 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 […]

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 or 5TE 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. 

Features
  • Continuous EC measurements in a pipe or tank
  • Direct measurements of pore water EC when used in conjunction with the Wetting Front Fullstop
  • Check your EC values anywhere with an internet connection
