What is pH ORP controllers and transmitter?
A pH ORP controller, also called a pH ORP transmitter, is a water quality monitor used to measure and control pH and ORP levels in water. Our controllers are used with pH/ORP sensors or electrodes and take the prepared measurements from the sensor online in real time.
pH: It is a scale of hydrogen ion activity in a solution and the most common measure of how acidic or alkaline a solution is. The lower the pH, the more acidic the solution; the higher the pH, the more alkaline the solution.
ORP: It is a measure of the tendency of a solution to gain or lose electrons in a reaction. A solution with a higher (more positive) reduction potential than some other molecule will have a tendency to gain electrons from this molecule (i.e. to be reduced by oxidizing this other molecule) and a solution with a lower (more negative) reduction potential will have a tendency to lose electrons to other substances (i.e. to be oxidized by reducing the other substance).
Working Principle
Using an online pH ORP controller with a sensor can monitor the pH/ORP value of different water bodies, and control the dosing pump through a relay to increase or decrease acid, alkali and other chemical substances to adjust the pH/ORP value of the water body to achieve the best treatment conditions. It can control the pH value of the water body according to the requirements of different treatment processes and improve the treatment effect. For example, after the sewage treatment is completed, when it needs to be discharged into the natural environment, if the pH value of the sewage is too high or too low, it will pollute the environment. Therefore, it is necessary to use a pHORP controller to control the discharge port to ensure that the pH value of the discharged sewage is within the required range and reduce environmental pollution.

What are the types of pH and ORP controllers?
They are mainly divided into digital controllers and analog controllers, and there are significant differences in many aspects.
Analog PH controller: It is based on the regulation of continuously changing physical quantities. These physical quantities are continuous in time and value. It is easy to adjust and has a simple structure. However, it also has many limitations, such as being susceptible to environmental interference and difficult to achieve remote monitoring.
Digital PH controller: It has the advantages of fast processing speed, strong anti-interference ability, flexible design, strong real-time performance, and easy to achieve remote monitoring and communication.
ORP controller: It is also based on this type of transmission of digital and analog signals.
Application areas
Water treatment: Control the pH and ORP values of drinking water, swimming pool water, industrial wastewater, and domestic sewage.
Food industry: Control the pH value during food processing to ensure the taste and safety of food.
Pharmaceutical industry: Control the pH and ORP values during drug production to ensure the quality of drugs.
Electroplating industry: Control the pH/ORP value of the electroplating solution to ensure the quality of the coating.
Aquaculture: Control the pH and ORP values of the water environment in aquaculture to provide a suitable growth environment for plants and improve aquaculture production and quality.
