Product Information
Online Ultra-Low Free Chlorine Monitoring Transmitter with CCF1.0 Sensor for RO Feed Water & Membrane Protection
Application
W519-DCCF1 is widely used in water treatment processes where strict control of free chlorine is critical for system safety and membrane protection.
Reverse Osmosis (RO) pretreatment and feed water monitoring
RO membrane protection systems (prevention of oxidation damage)
Desalination plants and industrial pure water systems
Drinking water disinfection monitoring
Swimming pool and recreational water disinfection control
In RO systems, the main objective is not chlorine dosing control, but ensuring complete dechlorination or maintaining ultra-low residual chlorine levels to protect sensitive membrane materials. W519-DCCF provides stable long-term monitoring under these low-concentration conditions.
