I. Measurement Principle

The ammonia nitrogen online automatic monitor determines the ammonia nitrogen content of the water sample by the salicylic acid spectrophotometric method, in full compliance with the national standard.

II. Instrument Description

The instrument is fully independently developed and owns its intellectual property. It is highly integrated, easy to maintain and highly automated. Reagent consumption is greatly reduced, which saves operating cost, and the smaller footprint reduces transport cost. A 7-inch colour touch screen with large memory and fast response is provided. The instrument offers automatic calibration, automatic range switching, reagent-shortage alarm and fault alarm. Cleaning liquid and waste liquid are kept separate, which greatly lowers the cost of waste disposal. Several measurement modes are available, a dedicated algorithm makes the measurement more accurate, and the dedicated reagent formulation gives strong resistance to ion, turbidity and colour interference.

III. Application

Widely used for the monitoring of industrial wastewater, domestic sewage and surface water.

IV. Instrument Features

1. Imported Japanese photoelectric dosing unit, reliable and stable with strong anti-interference capability.

2. Imported Japanese cold light source with no light intensity attenuation and a service life of more than 10 years.

3. Detector board made with imported Japanese components, giving high precision and low temperature drift.

4. PLC based on German Siemens technology.

5. Industrial-grade touch screen with strong environmental adaptability.

6. PTFE tubing resistant to strong acids and alkalis.

7. Optional: IoT remote control, allowing operation from a mobile app and making maintenance and after-sales service more convenient.

8. Optional: printing function.
