The Milwaukee MC125 is a professional pH and ORP controller, designed for use with aquariums to monitor and control pH levels and oxidation reduction potential in water.

The Milwaukee Instruments MC controllers have a user selectable set point and a visual "Power Activated" LED notification light. Power to the controller box is turned on when the reading is Above or Below the selected set point. These MC Controllers are ideal for CO2 or ozone dosing. This could be controlled by a solenoid valve (MA955).

With each Milwaukee Smart controller, your aquarium will have the individual attention that it needs.
