This chlorine residual sensor is designed for continuous online detection of residual chlorine in water. Equipped with high-performance platinum ring electrode and membrane-free amperometric technology, it features fast response and long service life. Automatic temperature and pH compensation effectively reduce water quality interference and guarantee reliable data.
It adopts standard RS485 Modbus-RTU communication, compatible with PLC, controllers and remote monitoring systems. IP68 fully submersible structure with 3/4" NPT thread for easy mounting. No consumables needed, low maintenance, suitable for long-term operation in water disinfection and water treatment projects.
MTW-ACC100 Chlorine Residual Sensor is a universal industrial probe for real-time detection of residual chlorine in water bodies. Adopting mature constant potential three-electrode technology, it features stable signal, fast response and excellent repeatability for long-term operation.
Built-in automatic temperature compensation effectively reduces measurement errors caused by water temperature changes. It supports standard RS485 Modbus RTU communication, which can be seamlessly connected with controllers, PLC and remote monitoring systems.
The no-membrane structure avoids the trouble of frequent membrane replacement, and only simple regular cleaning is required for daily maintenance. With IP68 fully sealed corrosion-resistant housing, it is applicable to submerged and flow cell installation in various water environments.
It is widely used in drinking water production, municipal water supply, swimming pools, industrial disinfection, reclaimed water and sewage treatment projects.
