The ES-2 Electrical Conductivity & Temperature Sensor is designed to measure the electrical conductivity (EC) and temperature of water in a pipe or tank. EC is useful for measuring salinity levels or quality of irrigation water.
The ES-2 can be installed in line with an irrigation pipe, in a water body, or in a tank.
