Milwaukee MC740 PRO Conductivity (EC) Controller and Pump Kit

The MC740 kit includes the MC311 EC controller and the MP810 dosing pump which automatically monitor and fine-tune EC levels.  Simply set EC parameters and let the Milwaukee EC Controller and pump do the rest.  The kit 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.

The Milwaukee PRO EC controller offers an accuracy to ±2% full scale.  The controller provides a control range of 0.0 to 10.0 mS/cm with alarms that activate when readings are higher or lower than set point.
