4、 Measurement principle and process

• Detection PrincipleUnder alkaline conditions, ammonia and ammonium ions in water samples react with salicylates and hypochlorous acid ions in the presence of sodium hydroxide to form colored compounds. By measuring the absorbance at a specific wavelength, the concentration of ammonia nitrogen is calculated according to Lambert Beer's law.

• Measurement process：

1. Water sample collection: The water sample is extracted by an injection pump, and after pre-treatment (sedimentation, filtration), it is sent to the metering unit;

2. Reagent reaction: Add reagent one (salicylate solution) and reagent two (hypochlorite solution) in sequence, and react at a constant temperature of 50 ℃ in the digestion chamber;

3. Photoelectric detection: The reaction solution enters the colorimetric cell, measures the absorbance, and converts it into ammonia nitrogen concentration;

4. Flow path cleaning: After measurement is completed, the pipeline and colorimetric cell are automatically cleaned to avoid cross contamination.

5、 Application scenarios

1. environmental monitoringMonitor the concentration of ammonia nitrogen in natural water bodies such as surface water, lakes, and rivers, grasp the trend of eutrophication in water quality, and provide data support for ecological governance.

2. sewage treatment plantReal time monitoring of ammonia nitrogen concentration in inflow/outflow to ensure that the discharge indicators comply with the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002).

3. industrial wastewaterMonitoring of wastewater treatment processes in industries such as chemical, printing and dyeing, and food, optimizing denitrification processes, and reducing treatment costs.

4. municipal water supplyMonitoring of ammonia nitrogen in source water and pipeline water to prevent algae growth and odor issues, ensuring safe drinking water.

6、 Maintenance and after-sales service

• routine maintenance：

• Check the remaining amount of reagents and the sealing of pipelines every week, and replace the filter element every month;

• Perform user calibration every 3 months and verify measurement accuracy using standard solutions;

• Regularly clean the measuring tube and colorimetric cell to avoid contamination from affecting the detection.

• troubleshootingCommon faults such as "abnormal liquid extraction" can be checked for reagent level and pipeline blockage; Abnormal heating "requires investigation of the connection between the heating wire and fan. For complex issues, please contact after-sales remote diagnosis.

• Service GuaranteeCore components come with a one-year warranty and lifetime technical support; National service network coverage, engineers come to repair within 48 hours, and provide free operation training and reagent preparation guidance.
