Milwaukee pH controller with CO2 - Model MC122 PRO - Professional PH Meter

The Milwaukee pH controller with CO2 control (MC122 PRO) allows you to continuously monitor the pH value and adjust the CO2 dosage accordingly. The solenoid valve (not included) of the CO2 system can easily be connected to the socket of the MC122 PRO. The pH electrode can then be placed in the aquarium and the desired pH value can be entered on the controller.

The system is now set up and the pH value is constantly monitored by the controller. If the pH value exceeds the set value, the solenoid valve is controlled to open further, adding more CO2 to the aquarium. When the set pH value is reached, the solenoid valve is closed and the CO2 supply stops.
