Constructed from high-strength polymer plastic, the analyzer resists chemical corrosion (e.g., acids, alkalis) and mechanical wear, ensuring reliable operation in wastewater treatment plants or marine environments.
Supports standard solution calibration with configurable forward/reverse curve algorithms, enabling precision tuning for specialized applications like aquaculture or pharmaceutical wastewater.
Isolated power supply design with built-in surge protection minimizes signal distortion, ensuring stable data transmission in complex industrial electromagnetic fields.
Designed for direct installation in surface water monitoring stations, sewage treatment lines, potable water distribution networks, and chemical plant effluent systems.
Compact structure and anti-fouling surface reduce cleaning frequency, while plug-and-play integration lowers deployment costs for large-scale monitoring networks.
Real-time NH₄⁺ monitoring to optimize biological treatment processes and ensure compliance with discharge standards (e.g., EPA, EU regulations).
Continuous tracking of ammonia nitrogen in rivers/lakes to identify pollution sources and support ecosystem restoration projects.
In-line monitoring of NH₄⁺ in chemical manufacturing, food processing, and metal plating effluents to ensure regulatory compliance.
Early detection of ammonia nitrogen in source water to prevent nitrogenous contaminant buildup in potable water systems.
Maintain optimal NH₄⁺ concentrations in fish farms to promote aquatic health and maximize yields.
Assessment of nutrient runoff from farmlands to support sustainable irrigation practices and water body protection.
