Conductivity (EC) Controller w/Mounting Kit, 0.8 to 2.8 mS/cm
The MC311 EC controller automatically monitors and fine-tunes EC levels. Just set your EC parameters and let the Milwaukee EC Controller do the rest.
The Milwaukee PRO EC controller is preferred by people looking to dial in their testing program when they have an ongoing need to maintain levels. Common uses are nutrient tanks and aquariums.
