Smart residual chlorine sensor residual chlorine analyzer - AMT-YL300

Smart residual chlorine sensor

is a kind ofConstant voltage methodorPolarographic methodPrinciple-based digital water quality analysis instrument for real-time monitoring of residual chlorine content in water bodies. It has a built-in microprocessor andRS485 digital interface, supportingModbus communication protocol, with automatic temperature compensation,Self-diagnostic function and zero-maintenance design, and can be widely used in scenarios such as drinking water, swimming pool water, and industrial circulating water.

Intelligent residual chlorine sensor residual chlorine detector

Core technical principle

The sensor is based onConstant voltage methodWorking: maintain a stable potential at the electrode measurement end. Different components in the water body generate current signals of different intensities under this potential, and the signal has a good linear relationship with the residual chlorine concentration, thereby calculating the residual chlorine or hypochlorous acid content in the water-1-12。

Its technical features are as follows:

Feature Dimensions	Technical description
Measurement principle	Constant voltage method (three-electrode system: working electrode, counter electrode, reference electrode)-1-5-6
信号输出	RS485 digital interface, supporting standard Modbus RTU protocol; some models also provide 4-20mA analog output-1-5-7
Temperature compensation	Built-in digital temperature sensor (such as Pt1000), automatically compensates for the influence of temperature on measurement values-1-4-12
Core advantages	No reagents, no membrane replacement, easy maintenance, response time usually <30 seconds

Typical application scenarios
The smart residual chlorine sensor is suitable for all occasions where disinfection effect monitoring and residual chlorine management of water bodies are required-1-4-5:

Drinking water treatment: residual chlorine monitoring at the outlet of water treatment plants and the end of the pipe network, ensuring drinking water safety-5-6.

Swimming pools and water parks: real-time detection of disinfectant residue, preventing bacterial growth, and protecting skin health-2-5.

Industrial circulating water: microbial control in cooling towers and boiler feedwater systems, preventing biological fouling-5.

Medical wastewater: residual chlorine monitoring in hospital sewage disinfection processes, ensuring compliant discharge-5-6.

🔍 Selection points
Determine range and accuracy: for drinking water monitoring, a low range of 0-2mg/L is commonly used-6; for industrial circulating water or sewage disinfection, 0-10mg/L or even higher may be needed-5-6. In terms of accuracy, ±5% error is generally acceptable in industrial sites-4-10, while laboratories or strictly monitored scenarios require higher accuracy-2-10.

Confirm output and integration: confirm whether the sensor output interface (RS485 Modbus is mainstream) is compatible with your PLC or SCADA system-1-3-5. Some models also provide 4-20mA analog output for easy integration into traditional control systems-5-7.

Evaluate environment and maintenance: according to the installation environment (such as humid, corrosive), choose an appropriate protection level (such as IP68 submersible-1-4 or IP65 splash-proof-5-7). Models with no reagents and long electrode life can reduce later maintenance costs-1-5.
