This digital pH controller offers a convenient way for you to monitor the various water parameters in your tank. With the electrodes in place, it can monitor the pH readings at all times while controlling the pH related devices (such as a CO2 system, air outlet stone,oxygen pump, electromagnetic valve). This unit comes with 2 bottles of calibration solution  to keep the controller always accurate. It can be connected to a CO2 system where it can control the solenoid valve to regulate the release of carbon dioxide in your environment.Once the desired pH is set and the unit sense’s a changes in pH level, the relay steered control output sends a signal to the solenoid valve.The CO2 regulator will adjust the release of carbon dioxide until it reaches the set pH.

This fully automatic system helps stabilize your water pH by adding an appropriate amount of CO2 to your aquarium. This system includes a pH controller so you don’t have to monitor the amount of CO2 being released into your aquarium. This pH controller will keep pH and CO2 releases consistent and appropriate for your aquarium.

This can be used for every purpose, from a goldfish bowl to a full blown reef tank. It can also be used for fish hatcheries, wine production, swimming pools, floristics, analysis of fluids (ph-value), ponds and various industrial applications.
