Nexisense NHN-406-A Online Ammonia Nitrogen Sensor Product Definition
The Nexisense NHN-406-A Online Ammonia Nitrogen Sensor is a high-performance instrument designed specifically for detecting ammonia ions in water. It can quickly and accurately measure the concentration of ammonia nitrogen in water, widely used in environmental monitoring, wastewater treatment, and industrial water quality control.
Measurement Principle
This sensor employs the ammonia ion selective electrode method for measurement. The ammonia ion selective electrode utilizes a PVC membrane's selectivity for ammonia ions, enabling accurate detection of ammonia ion concentration in complex water quality. The built-in temperature compensation system ensures the accuracy and stability of measurement results under varying temperature conditions.
Structure Analysis
The Nexisense NHN-406-A features a well-designed structure, primarily composed of the following components:
Shell Material: Made of corrosion-resistant ABS, PVC, and POM materials, ensuring durability in various environments.
Ammonia Ion Selective Electrode: The core measurement component that effectively separates ammonia ions, providing accurate measurement results.
Temperature Compensation Element: Built-in Pt1000 temperature sensor that automatically adjusts measurement results to ensure accuracy.
Signal Output Interface: Supports RS-485 (Modbus RTU) and 4-20mA outputs, facilitating easy connection to PLC, DCS, and other industrial control systems.
Measurement Method
The Nexisense NHN-406-A supports multiple measurement ranges:
0 to 10.00 mg/L, resolution 0.01 mg/L, accuracy ±10% or ±1 mg/L (whichever is greater)
0 to 100.00 mg/L, resolution 0.01 mg/L
0 to 1000.0 mg/L, resolution 0.1 mg/L
The sensor's response time (T90) is less than 60 seconds, allowing for quick responses to changes in water quality, making it suitable for real-time monitoring needs.
