Intelligent Water Quality Residual Chlorine Sensor Modbus RTU Output, Suitable for Solar Buoys and Online Monitoring Systems
Product Introduction:
In scenarios such as drinking water safety, swimming pool hygiene, and industrial water treatment, residual chlorine concentration serves as the core control indicator for disinfection effectiveness, directly related to water quality compliance and public health. This RS485 digital residual chlorine sensor is specially designed for harsh applications such as water treatment plants, pipe network terminals, medical wastewater treatment, and swimming pool circulating water. With three core advantages of RS485 digital output, membrane free/constant voltage measurement, and precise stability, it helps you control the real-time disinfection status of water bodies 24/7.
Core Advantage:
① Digital signal output, worry free system integration
Using standard Modbus RTU protocol RS485 communication output, it can directly connect to third-party devices such as PLC, DCS, industrial control computer, and touch screen, without the need for additional instruments to complete data acquisition and remote monitoring. Strong resistance to environmental interference, with a communication distance of up to 1200 meters, making it easy for large-scale network deployment.
② Constant voltage/three electrode system, low maintenance and high precision
Adopting non membrane constant voltage or three electrode electrochemical principle, there is no need to replace the membrane and chemical agents, and there is no reagent consumption or secondary pollution. Measurement range: 0-20mg/L, resolution: 0.01mg/L, built-in temperature compensation algorithm, automatically eliminates temperature effects, ensuring accurate and reliable long-term operation data.
③ Durable and sturdy, suitable for harsh environments
Fully sealed POM/ABS shell, with a protection level of IP68, can be submerged in water for a long time, with a water depth support of over 20 meters. NPT 3/4 thread installation design, supporting immersion, pipeline or flow pool installation, flexibly adapting to various on-site conditions.
④ Wide voltage power supply, low-power operation
The power supply voltage is 12-24VDC, and the overall power consumption is less than 0.2W, making it very suitable for long-term unmanned online monitoring node deployment, effectively reducing system operation and maintenance costs.
