In fields such as aquaculture, industrial wastewater treatment, river and lake monitoring, and sewage treatment, multi-parameter water quality analyzers have become indispensable core equipment in project implementation. NiuBoL multi-parameter water quality analyzer provides fast, accurate, and stable synchronous detection of multiple indicators for system integrators, IoT solution providers, project contractors, and engineering companies. It supports monitoring of key parameters such as ammonia nitrogen, nitrite, dissolved oxygen, residual chlorine, phosphate, pH, conductivity, turbidity, etc. It adopts Android intelligent operating system and modular design, easy to integrate into online monitoring platforms, smart water affairs systems, and environmental IoT projects, enabling real-time data upload, remote management, and intelligent early warning.

With the large-scale development of aquaculture and increasingly strict regulation of industrial wastewater discharge, water quality has become a key factor restricting production efficiency, ecological safety, and compliance. Traditional single-parameter detection can no longer meet comprehensive evaluation needs. Multi-parameter water quality analyzers obtain multiple physical and chemical indicators synchronously with one sampling, providing data support for precise regulation.
In aquaculture, indicators such as dissolved oxygen, ammonia nitrogen, and nitrite directly affect fish and shrimp survival rate and growth speed; in industrial sewage and sewage treatment scenarios, monitoring of COD, total phosphorus, ammonia nitrogen, etc., is the basis for meeting the Surface Water Environmental Quality Standard (GB 3838-2002) and pollutant discharge permit requirements. NiuBoL products adopt rapid color development method combined with electrochemical/optical sensors, with short detection cycle and good repeatability, particularly suitable for engineering projects requiring high-frequency monitoring.
NiuBoL multi-parameter water quality analyzer is specially designed for industrial-grade applications, with the following engineering characteristics:
Multi-parameter synchronous detection: Supports ammonia nitrogen, nitrite, dissolved oxygen (DO), residual chlorine, phosphate, hydrogen sulfide, total alkalinity, pH, conductivity, turbidity, and other indicators (specific configuration customized according to project needs)
Operating platform: Based on Android intelligent operating system, intuitive interface, supports touch screen operation, data curve display, historical record query and export
Detection method: Combined with dedicated rapid color development reagents, achieves “fast-simple-accurate-stable” measurement, single detection time generally 5-15 minutes
Protection and adaptability: IP65 or higher protection level, suitable for complex environments such as outdoors, factory areas, pumping stations
Data interface: Standard RS485 (Modbus RTU protocol), 4G/5G wireless module, supports MQTT, HTTP and other protocols, easy to access SCADA, cloud platforms or environmental regulatory systems

Engineering companies can integrate the instrument into mobile monitoring vehicles, fixed monitoring stations, or unattended pumping stations, achieving full-process automation from sampling-analysis-transmission-visualization-alarming.

1. Large-scale Aquaculture Bases
High-density breeding ponds are prone to ammonia nitrogen and nitrite accumulation, insufficient dissolved oxygen leading to large-scale fish death. NiuBoL system monitors multiple indicators in real time, linking aeration equipment and water exchange pumps for automatic regulation. After integration in a ten-thousand-mu shrimp and crab breeding project in East China, disease incidence decreased by about 35%, and feed conversion rate improved significantly.
2. Industrial Park Sewage Treatment Stations
Chemical, electroplating, printing and dyeing industries have complex wastewater components, requiring strict monitoring of ammonia nitrogen, total phosphorus, COD, etc. The instrument's rapid detection capability supports process optimization and compliance discharge judgment, with platform achieving 24-hour continuous monitoring to meet local environmental supervision requirements.
3. River and Lake Ecological Monitoring and Water Source Protection
Deployed at river inlets and lake reservoir sections for long-term online monitoring of ammonia nitrogen, total phosphorus, turbidity, etc. Project cases show that after integrating GIS maps, pollution sources can be quickly located to assist comprehensive river basin management.
4. Swimming Venues and Municipal Water Supply Secondary Pressurization
