onlinePH/ORP controllerIt is an automated instrument used for real-time monitoring and adjustment of liquid pH and oxidation-reduction potential (ORP), widely used in industrial water treatment, environmental monitoring, food and beverage production, chemical, pharmaceutical and other fields.

Basic composition:

Sensor: It is the core part of the controller, including pH electrodes and ORP electrodes, responsible for sensing changes in pH or ORP values and converting them into electrical signals.

Signal processing unit: converts analog signals from sensors into digital signals and compares them with set target values to determine whether control parameters need to be adjusted.

Control module: Output control instructions based on processed signals, such as opening or closing pumps, valves, or dosing devices.

Display and operation interface: usually equipped with a display screen, real-time display of pH value, ORP value, set value, control status and other information, and providing manual or automatic adjustment operation interface.

Alarm system: When the pH or ORP value deviates from the set range, an alarm prompt is issued.

　　onlinePH/ORP controllerApplication scenarios:

Municipal water supply system: used for monitoring water at the end of the pipeline network, requiring high-precision measurement of 0.01-14pH and automatic calibration function to ensure long-term operational accuracy.

Chemical production process: It is necessary to deal with strong acids, strong alkalis, and highly corrosive media. The controller often uses corrosion-resistant materials and is linked with the dosing system through signals to achieve automatic adjustment of acid-base neutralization.

In the field of environmental monitoring: In surface water and lake monitoring, it is necessary to adapt to complex outdoor environments, often using solar power supply, with high protection level, and can resist short-term flooding.
