Nexisense NHN-206 Online Ammonia Nitrogen Sensor Product Definition
The Nexisense NHN-206 Online Ammonia Nitrogen Sensor is a high-performance water quality monitoring device specifically designed for measuring ammonia ion concentrations in water. It employs the latest PVC membrane-based ion-selective electrode technology, enabling rapid and accurate acquisition of ammonia nitrogen concentration information, making it widely applicable in industrial wastewater treatment, environmental monitoring, and water resource management.
Principle
The NHN-206 sensor utilizes the ion-selective electrode method, where its working principle is based on the selective adsorption of ammonia ions at the electrode surface. When the water sample containing ammonia ions contacts the electrode, it generates a voltage signal proportional to the concentration of ammonia ions. This signal is processed internally and converted into a digital output representing the ammonia nitrogen concentration, thereby enabling real-time monitoring.
Structural Analysis
The NHN-206 Online Ammonia Nitrogen Sensor is designed to ensure long-term stability and usability. The sensor's casing is made from corrosion-resistant ABS, PVC, and POM materials, making it suitable for various harsh environments. The internal reference electrode system is designed with a microporous salt bridge that reliably releases the internal reference solution, thereby extending the electrode's lifespan.
Nexisense NHN-206 Online Ammonia Nitrogen Sensor Measurement Method
| Measurement Range | Resolution | Accuracy |
|---|---|---|
| 0 to 10.00 mg/L | 0.01 mg/L | ±10% of reading or ±1 mg/L (whichever is greater) |
| 0 to 100.00 mg/L | 0.01 mg/L | ±10% ±0.5℃ |
| 0 to 1000.0 mg/L | 0.1 mg/L | ±10% ±0.5℃ |
The sensor can be calibrated using a two-point calibration method to ensure high precision across different measurement ranges. It also features a fast response time, typically completing measurements within 60 seconds.
