The online chloride ion analyzer utilizes the ion-selective electrode (ISE) method to acquire chloride ion data

Designed for real-time detection of chloride ions in water, the analyzer features a measurement range of 0 to 3500.0 mg/L with an accuracy of ±5%. It includes temperature compensation (±0.3°C) and offers a resolution of 0.1 mg/L, ensuring stable and reliable response performance. The device supports the integration of additional multi-parameter sensors, allowing users to configure various water quality monitoring modules based on specific on-site requirements. It automatically stores monitoring data and alarm records, with support for data export to facilitate record-keeping and traceability. Equipped with an RS485 communication interface and compatible with the MODBUS-RTU protocol, the analyzer can be directly connected to PLCs, DCS, SCADA/configuration software, or DTU devices, enabling remote data transmission and centralized management.

By employing the ion-selective electrode method, the analyzer delivers high sensitivity, rapid signal feedback, and stable measurement results. It requires minimal routine maintenance and is capable of continuous, long-term operation, making it well-suited for uninterrupted on-site monitoring. Chloride ion concentration is a critical control parameter in settings such as wastewater treatment plants, waterworks, surface water monitoring stations, and the discharge outlets of industrial and mining enterprises. Excessive chloride levels can accelerate the corrosion of pipelines and equipment, while also impairing the efficiency of water treatment processes. This online analyzer provides a continuous stream of reliable data, enabling personnel to stay informed of water quality fluctuations; it can also trigger alarms when parameters exceed set limits, thereby mitigating risks associated with water quality management.

The analyzer’s structure is engineered to withstand industrial operating environments. It eliminates the need for frequent manual sampling and laboratory analysis, thereby reducing the time lag and human error inherent in manual testing. Its modular configuration lowers the cost of future upgrades, while standardized communication protocols simplify integration and development. Furthermore, the data storage and export capabilities satisfy requirements for environmental compliance documentation and production management records, making it a highly practical solution for routine, online monitoring of chloride ions in water.
