Milwaukee MC122 pH Controller

The MC122 is a professional pH controller of European manufacture. Perfect for connecting to your Co2 set. By using a pH controller, you prevent an excess of Co2 in the aquarium water with all its consequences.

Connect a solenoid valve to the power strip of the pH controller, place the electrode in the aquarium, and set the pH value. Before using the controller, it is advisable to calibrate it with the supplied liquid sachets.

The pH controller continuously measures the current pH value of the aquarium. If it exceeds the set value, it opens the Co2 until it reaches the set value. After this, it automatically shuts off the Co2 supply.

We do not work without these Controllers and are very pleased with their quality and ease of use.

Set includes the pH electrode.

PLEASE NOTE! The controller CANNOT be used with a 12-volt solenoid valve. These are also sold by other brands; you can recognize them by a USB power source.

Our Co2 sets and other accessories ARE, of course, suitable for this pH computer.
