Basic concept of building energy efficiency

The pH ORP controller is an effective Water Quality Monitor used to accurately measure and online control pH/ORP parameters in aqueous solutions. The pH ORP controller, also known as the pH ORP transmitter, has two 0/4-20mA current outputs, supports remote signal transmission control and long-term pH/ORP calibration. It has a two-wire RS485 interface and can be easily connected to a computer for monitoring and recording via the MODBUS-RTU protocol.

 

pH and ORP are two key parameters in water quality monitoring. pH, or acidity, is an indicator of the strength of the acidity and alkalinity of aqueous solutions. Its value is usually between 0 and 14, with 7 indicating neutrality, less than 7 indicating acidity, and greater than 7 indicating alkalinity. The pH value of water quality has an important impact on many chemical reactions, biological processes, and equipment operation. Too high or too low pH values ​​may lead to deterioration of water quality and affect the ecological environment or industrial production. ORP, or redox potential, is an indicator of the redox capacity of aqueous solutions. It reflects the relative concentrations of oxidants and reductants in water and is an important parameter for evaluating the redox state of water quality. The high or low ORP value can affect the activity of microorganisms in water, the oxidation and decomposition of organic matter, and the dissolution and precipitation of metal ions. Therefore, in order to ensure the stability of water quality and meet specific requirements, we use pH ORP controllers to monitor and control these two parameters online. Through real-time measurement and adjustment, water quality abnormalities can be discovered and handled in a timely manner to ensure that the water quality is in the best state and meet the needs of water quality in different fields.

 

 

As an online dosing control pH controller, the control function is very important. Our controllers are equipped with 2 relays that can be set by SPST. Customers can set the opening value and closing value to realize the control of the acid-base dosing pump, temperature and cleaning control.

 

The sensor probe is immersed in the solution, such as a swimming pool, fish pond, or water tank. It sends real-time readings to the controller, which processes and displays the values. Users can pre-set upper and lower limits on the controller for either pH or ORP. If the sensor detects that the solution's pH or ORP value exceeds these limits, the controller sends a signal to the dosing pump. The pump then injects chemicals into the solution to restore the value to the acceptable range. The system uses a feedback loop to continuously adjust dosing and maintain the ideal chemical balance.

 

 

For the convenience of customers, the small-sized pH controller also adds a quick calibration button. The calibration of the pH ORP controller is also very important. It is usually recommended that the electrode needs to be calibrated every 7 days. Our pH meter transmitter supports pH three-point calibration, ORP two-point calibration, and the calibration point can be set by yourself.

 

 

As an efficient and accurate monitoring device, the PH/ORP controller has been widely used in many industries such as thermal power, fertilizer, environmental protection, pharmaceuticals, and tap water. It can be equipped with a suitable PH Sensor or ORP Sensor according to actual needs to continuously and real-time monitor the pH value or ORP value in the solution. At the same time, the controller can also monitor the temperature of the solution, providing comprehensive and accurate data support for the production process of related industries. In addition, we have also launched a solution ground pH meter, which is particularly suitable for monitoring pure water in power plants. It can be closely connected with the SG sensor to achieve accurate measurement of the pH value of pure water in power plants, providing a strong guarantee for the safe and efficient operation of power plants.
