ROC 8221 Reverse Osmosis Controller (2x EC Probes)

ROC 8221 Reverse Osmosis Controller
 
The Reverse Osmosis Controller ROC-8221 (CCT-8320 / ROC-8221A) is a highly efficient and advanced process controller specifically designed for reverse osmosis systems. It combines a single-stage reverse osmosis controller and a double-channel on-line conductivity instrument, offering superior performance and functionality.
 
With an inlet range of 4000us/cm and an outlet range of 200us/cm, this controller ensures precise monitoring and control of water conductivity levels throughout the reverse osmosis process. It comes equipped with a safe DC24V power supply, guaranteeing reliable and stable operation.
The ROC-8221 features a large LCD screen that displays important information such as inlet water quality, producing water quality, water temperature, and desalinization ratio.
 
The user-friendly interface and menu-driven operation simplify usage, allowing for easy parameter setting and modification.
 
With its multiple controlling modes, this controller meets the requirements for automatic operation of reverse osmosis systems. Whether it's operational testing, status control, or real-time water quality monitoring, the ROC-8221 ensures efficient and effective management of your reverse osmosis process.
