Product OverviewW519-DCCF1 is an online free chlorine monitoring system combining the W519 transmitter and a high-stability DCC1 amperometric free chlorine sensor. Designed for continuous measurement in RO feed water and membrane protection applications, it detects residual free chlorine down to 0.05 mg/L with fast response, strong signal stability and no reagents required. The sensor is optimized for long-term operation in low or zero chlorine environments and the transmitter supports industrial communications and low maintenance operation.
