Recently, NiuBoL's independently developed and produced NBL-WQ-CLI-4 split-type online chloride ion sensor was successfully exported to the Swedish market and applied in local water treatment and environmental monitoring projects. This successful entry of the product into the Nordic market not only reflects international customers' recognition of NiuBoL's product quality and technical strength, but also marks a new breakthrough in the company's internationalization layout in the European environmental monitoring field.
As global requirements for water resource protection and environmental governance continue to increase, real-time, precise, and stable water quality monitoring equipment is becoming an important component of modern water treatment systems. NiuBoL's online chloride ion sensor, with its excellent performance and reliability, provides customers with all-weather online monitoring solutions to help achieve more intelligent and efficient water environment management.

Sweden is located in the Nordic Scandinavian Peninsula and is one of the pioneers in the field of global environmental protection and sustainable development. With comprehensive environmental protection regulations and advanced infrastructure construction, Sweden has always maintained a world-leading level in drinking water safety, sewage treatment, industrial wastewater treatment, and ecological environment protection.
As one of the European countries with higher environmental protection standards, Sweden has strict requirements for the accuracy, stability, and long-term operation capability of online monitoring equipment. Especially in the fields of municipal water utilities, industrial circulating water, and environmental monitoring, high-quality online analysis instruments have become important equipment to ensure the safe operation of systems.
The successful entry of NiuBoL's products into the Swedish market fully proves that the company's products can meet the needs of European customers for high-reliability water quality monitoring equipment.
Chloride ion is one of the common and important ions in water bodies, and its concentration changes directly affect equipment operation safety and water quality management effectiveness.
In practical applications, excessively high chloride ion concentrations may lead to:
Accelerated corrosion of metal pipelines;
Shortened service life of boilers and heat exchange equipment;
Impact on industrial production processes;
Decreased operating efficiency of water treatment systems;
Increased risk of exceeding environmental emission standards.
Therefore, continuous online monitoring of chloride ion concentration is of great significance for ensuring stable system operation, reducing maintenance costs, and improving management efficiency.
NBL-WQ-CLI-4 adopts solid membrane ion selective electrode technology and is specially used for online measurement of free chloride ions in water, enabling fast, accurate, and stable real-time monitoring.
The product adopts industrial-grade design and can be applied for a long time in complex working conditions, providing users with reliable data support.

The product is equipped with a patented chloride ion electrode. The internal reference solution is slowly released through a microporous salt bridge under 100KPa (1Bar) pressure, forming a stable reference system.
Compared with traditional industrial electrodes:
Higher measurement stability;
Smaller drift;
Longer service life;
Lower maintenance frequency.
This means customers can effectively reduce later operation and maintenance costs and improve the long-term operational reliability of the equipment.
The sensor T90 response time is less than 60 seconds, enabling quick capture of water quality change trends.
For projects requiring continuous online monitoring, fast response capability helps to:
Timely detection of abnormal situations;
Optimize process control;
Improve operational management efficiency;
Reduce potential operational risks.

The product supports:
RS-485 communication
Modbus RTU protocol
4-20mA analog output (optional)
It can be easily connected to:
PLC control systems
DCS systems
Industrial computers
SCADA monitoring platforms
Paperless recorders
Touch screen control systems
Helping users quickly complete system integration and project deployment.

NBL-WQ-CLI-4 online chloride ion sensor adopts a sturdy and reliable structural design with a protection rating of IP68.
It also supports:
Submersible installation
Pipe installation
Tank installation
Suitable for complex industrial environments and long-term outdoor monitoring applications.
1. Municipal water plants
