RS485 220V AC Online PH ORP Controller with temperature compensation 500g
In the sewage treatment system, in order to achieve the best treatment effect, but also to protect the safe operation of the process equipment, so as to prevent excessive acid or alkali media from entering the system and causing damage to the water treatment equipment, an online installation must be installed at the system water inlet The pH meter monitors and tracks the pH of the water in real-time, and adjusts the pH of the water. Therefore, the rational use and maintenance of online pH ORP controllers play a very critical role in water treatment. In addition, it is also widely used in chemical, light industry, and environmental protection fields.
Product Introduction
2 high-precision 0/4~20mA current output;
A two-wire RS485 interface;
Shortcut keys to perform necessary daily maintenance without entering the menu;
Menu passwords can be set for easy hierarchical management;
Power off protection, indefinite retention of parameters;
The communication protocol is Modbus RTU.

Advantages Of The PH ORP Controller
1.There are two SPST multifunctional relays that can be set up, including alarm for high and low PH/OPR value, alarm for high and low water sample temperature, or control of sensor cleaning cycle. In a bad environment, it can also be set as a warning to the working environment temperature of the instrument as an auxiliary means of hazard protection.
2.The pH ORP controller can not only compensate the temperature of the test sample by connecting the temperature sensor, but also self-check the working temperature of the instrument in real-time. When the working temperature of the instrument changes, the instrument compensates the hardware change caused by the temperature drift. Make the test results more accurate, this is a patented technology.
Applications Of The PH ORP Controller
Water treatment monitoring: Drinking water, surface water, water quality, groundwater, swimming pool, etc.
Industrial process monitoring and dosing control management: Chemical, petroleum, paper, food and medicine, electroplating, PCB manufacturing, etc.
