Milwaukee MC311 PRO Conductivity (EC) Controller

Overview

The Milwaukee MC311 PRO is a conductivity (EC) controller for automatically maintaining nutrient strength in hydroponic and greenhouse systems. It continuously measures EC from 0.0 to 10.0 mS/cm and, using an adjustable setpoint, activates dosing (with the optional MP810 pump) whenever the reading drifts from the target level.

Automatic temperature compensation keeps readings accurate from 0 to 50 °C, and the supplied MA812/2 probe installs directly in the nutrient line or tank. The wall-mountable controller runs from a 12 VDC adapter for continuous operation.
