The ammonia nitrogen concentration is accurately measured via the ion selective electrode (ISE) method—a gold-standard technology for water quality analysis. The integrated ammonia nitrogen sensor integrates four key functional electrodes: ammonium ion selective electrode, optional potassium ion electrode, high-precision pH electrode, and real-time temperature electrode. This multi-parameter synergy enables mutual correction and dynamic compensation of ammonia nitrogen measurements, eliminating errors caused by environmental fluctuations and ensuring data reliability. Meanwhile, it supports simultaneous multi-parameter monitoring (NH4-N, K+, pH, Temp.), meeting comprehensive water quality analysis needs for industrial and environmental applications.
✅ Dynamic Environmental Compensation: Real-time correction of temperature and pH variations in samples, maintaining measurement accuracy even in complex water matrices.
✅ Industrial-Grade Digital Sensor: Strong anti-interference capability (resists electromagnetic and chemical interference), long-distance signal transmission (compatible with extended cables), and stable performance in harsh conditions.
✅ Plug-and-Play Integration: Standard digital signal output (no additional transmitter required) for seamless networking with PLC, SCADA systems, and IoT platforms—simplifying system integration.
✅ Easy On-Site Installation: User-friendly design enables quick deployment, reducing installation time and labor costs.
✅ Dual Protection Mechanism: Power reverse polarity protection and RS485 A/B terminal power protection, extending sensor service life.
✅ Intelligent Data Management: Optional time display, built-in data storage, and historical data retrieval function—facilitating traceability and analysis.
✅ Wireless Connectivity Option: Optional data wireless transmission module (supports IoT integration) for remote monitoring and cloud data access.
• Sewage Treatment Plants: Aeration tank ammonia nitrogen monitoring, effluent quality control, and process optimization instruments.
• Industrial Processes: Water quality monitoring in chemical, pharmaceutical, food & beverage, and petrochemical industries (e.g., wastewater treatment, process water monitoring).
• Environmental Monitoring: River water, lake water, and surface water ammonia nitrogen detection; ecological environment protection and water resource management.
• Other Scenarios: Agricultural runoff monitoring, aquaculture water quality control, and municipal water supply network testing.

Measurement Principle
The ammonia nitrogen concentration was measured by an ion selective electrode method. The ammonia nitrogen sensor is composed of an ammonium ion selective electrode, a potassium ion (optional), a pH electrode and a temperature electrode to form an integrated sensor. These
parameters can mutually correct and compensate the measurement
value of ammonia nitrogen, and at the same time realize multi-
parameter measurement.
Features
Sensor can dynamically compensate temperature and pH in samples
Digital sensor, strong anti-interference ability, long transmission distance
Standard digital signal output for integration and networking with other devices without a transmitter
The sensor is easy to install on site, enabling plug and play
The sensor power supply is reversed and protected. The sensor RS485 A/B terminal is connected to the power supply protection.
Optional time display, data storage and historical data viewing
Optional data wireless transmission module
Applications
Sewage treatment plants monitoring instruments and ammonia nitrogen values in aeration tanks monitoring
instruments
Industrial processes and river water monitoring instruments .
