Ammonia nitrogen analyzer, ammonia nitrogen detector - Environmental certification

Ammonia nitrogen analyzer, ammonia nitrogen detector - certified for environmental protection

Ammonia nitrogen analyzer,Ammonia nitrogen analyzer, ammonia nitrogen detector - [KNF-502]It is mainly applied to surface water launched by Kenaf Technology The equipment for online monitoring of water quality and ammonia nitrogen in groundwater, drinking water sources, river sections, and fixed pollution source emissions adopts independent specialized technology and specially designed "automatic injection dilution"The "release technology" and "automatic injection and dose measurement" technologies, combined with proprietary reagent formulas, have solved the problem of short shelf life of traditional "salicylic acid method" reagents, and can operate in a 35 degree environmentA good formula that does not deteriorate for 40 days and does not deteriorate for 20 days in a 40 degree environment,

At the same time, compared toThe advantages of "Nessler's method" and "ammonia gas sensing method", as well as Kenaf's "salicylic acid method", include more stable measurement, high sensitivity, low detection limit, and non-toxic reagents. Make maintenance easier and lower cost operation and maintenance expenses.

The working principle of KNF-501COD analyzer adopts a combination of salicylic acid method and spectrophotometry technology. Under alkaline conditions, ammonia and ammonium ions in the sample react with hypochlorite ions to form ammonium chloride. At 40 degrees Celsius and in the presence of a catalyst, ammonium chloride reacts with salicylate to form a blue-green complex. Its absorbance is measured at 660nm wavelength and converted into the corresponding concentration value.

Simultaneously combiningThe "background absorption and turbidity calibration" technology reduces the impact of blackening or discoloration of water samples and turbidity on measurement, successfully solving the problem of "precipitation caused by masking agent potassium tartrate sodium and certain interfering ions under special working conditions, resulting in abnormal measurement".
