Description

Product Description

RO system is the abbreviation of reverse osmosis system. It is a phenomenon that creates an osmotic pressure difference between solutions with different solute concentrations through a semipermeable membrane, causing water molecules to permeate from the high concentration side to the low concentration side. RO systems are widely used in water treatment, food and beverage, pharmaceutical and other industries to remove most harmful substances and minerals in water and provide pure water. During the operation of the RO system, it is very necessary to monitor the pH value of water quality. daruifuno's online pH meter controller is designed for real-time continuous monitoring of water quality pH value, and the intelligent controller can also adjust the pH value. Make the water quality meet the requirements.

APX2-C1 online pH controller has two SPST settable relays. The user first sets the required pH value range, that is, the high and low alarm values, connects the dosing pump to add the liquid, and the PH Sensor detects the pH of the water quality, and Displayed on the pH controller. The controller automatically compares the measured value with the set value. When the alarm value is reached, the relay will be automatically turned on to control the dosing pump to add medicine, adjust the pH value of the water sample, and control it within the target range. Compared with Daruifuno's APX1 series controller, the APX2 series pH/ORP controller has a larger appearance. In addition to being able to be installed in a panel, it also supports wall-mounted, pipe and other installation methods.

In the RO system, there are the following links that need to monitor the pH value:
1. Before the raw water enters the RO system, the pH value of the raw water needs to be monitored, and the relay function of the pH controller is used to automatically adjust the pH value to a pH range suitable for the RO membrane to work.
2. During the operation of the RO system, the pH value of the water quality in the system needs to be monitored in real time to ensure that it is within the appropriate range and to prevent damage to the RO membrane due to too high or too low pH value.
3. The pH value of the RO system water outlet needs to be monitored to ensure that it reaches the preset or standard water quality.
4. When cleaning and disinfecting the RO system, it is necessary to monitor the pH value of the cleaning solution and disinfectant solution to ensure that they are within an effective and safe range.
