ES2 Electrical Conductivity and Temperature Sensor

Complete the electrical conductivity picture.

The ES2 Electrical Conductivity Sensor is designed to measure the electrical conductivity of water in a pipe or tank.  When you pair the new ES2 with a TEROS 12 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.
