How it works:
This PH controller is used to control PH value of liquids, ponds, aquaria etc. This means that a desired PH value can be set and stabilized. This PH controller has a probe measuring the PH of liquids, ponds, aquariums etc. A chosen value is memorized in the controller; and when the actual PH of liquids, ponds, aquariums changes, the controller activates an electrical outlet. This outlet can be connected to a random device, eg. an oxygen pump 、 co2 pump or an electromagnetic valve. Once the memorized value is reached again, the outlet is disconnected and also the device that makes the PH rise or drop.
