Milwaukee PH Controller MC122

Product details

Milwaukee PH Controller MC122 is a professional aquarium pH controller designed to help manage CO2-driven pH changes in reef and freshwater setups. It monitors tank pH with an included double-junction pH electrode and then controls dosing based on a user-selected pH set point. With manual 2-point calibration, it’s intended to be adjusted to your measuring needs for consistent readings, and the controller provides a clear visual alarm when the pH moves above or below the selected threshold. Overall, it’s a practical way to automate pH stabilization routines using a CO2 solenoid/dosing connection.

Features:

• User selectable high/low set point to define the pH target range
• Manual 2 points calibration for more reliable pH measurements
• Visual LED alarm that activates when readings go above or below the set point
