This Chlorine Sensor 0-20 mg/L is a wide-range industrial probe for free chlorine monitoring. It applies membrane-free amperometric technology, requiring no membranes or chemical reagents. Built-in automatic temperature and pH compensation to guarantee accurate readings amid changing water quality.
Standard RS485 Modbus-RTU digital output for seamless connection with controllers and PLC. IP68 submersible rating, 3/4" NPT thread for quick installation. Low maintenance, stable performance for 24/7 continuous operation in water disinfection systems.
MTW-ACC100 Chlorine Sensor 0-20 mg/L features a standard measuring range of 0 to 20mg/L, suitable for most conventional chlorine monitoring scenarios. It adopts reliable electrochemical sensing principle, delivering quick response, high precision and stable measurement performance.
Built-in temperature compensation function effectively corrects data deviation caused by fluctuating water temperature. Equipped with standard RS485 MODBUS-RTU digital output, it is easy to connect with controllers, PLC and remote monitoring systems.
The sensor is fitted with anti-fouling diaphragm and IP68 fully sealed structure, which resists dirt and corrosion. It supports long-term submerged installation and minimizes routine maintenance work.
It is widely used in tap water plants, swimming pools, reclaimed water systems, industrial disinfection water and municipal water pipeline monitoring.
