Designed for disinfection safety in drinking water and industrial circulating water, these sensors monitor free chlorine, residual chlorine, or total chlorine concentration. Using advanced potentiostatic measurement principles, they do not require frequent chemical reagent addition, significantly reducing operating costs. Through precise feedback signals, they automatically adjust chlorination pump dosing, balancing disinfection effectiveness with the risk of chemical over-limit or corrosion.
The SensorsX SX-CRCNA Series Residual Chlorine Sensor is designed for reliable free chlorine measurement in water treatment and disinfection processes. It provides a 0–20 mg/L measurement range with ±0.02 mg/L accuracy, and supports RS-485 / Modbus-RTU communication. With IP68 protection, built-in calibration parameters, and a durable 316L stainless steel housing, it is suitable for continuous industrial water quality monitoring.
