Ammonia Nitrogen AnalyzerThere are two measurement methods, one is the colorimeter method and the other is the electrode method. The principle of colorimetric method is that ammonia nitrogen will undergo stable changes with reagents in water, and this change is proportional to the sample concentration; The electrode method first measures the initial potential value of the sample, then adds a certain concentration of standard solution and measures the potential value of the mixed solution. The sample concentration is calculated based on the difference between the two measurements.
Ammonia Nitrogen AnalyzerAll of them have independent pipelines for high-precision measurement, and the structure is simple and clear, with low maintenance costs. Unlike other instruments and equipment, online ammonia nitrogen analyzers can be used without calibration during secondary use and can obtain stable and accurate results. The instrument itself comes with data storage capability, making it easy for experimenters to conduct data statistical analysis. Some ammonia nitrogen analyzers can also be remotely controlled.
Ammonia Nitrogen AnalyzerTechnical advantages:
1. Can self dilute high concentration samples
2. Can be controlled automatically for a long time without the need for laboratory personnel to be present, improving their work efficiency, and supporting long-term standby mode
3. Reduced the consumption of reagents and drugs, and the detection time generally only takes a few minutes to more than ten minutes
4. The electronic system is isolated from the power section to ensure the safety of the instrument
5. Temperature range in working environment: 0 ℃~40 ℃. If the laboratory must turn on air conditioning in winter and summer, the ammonia nitrogen analyzer is sensitive to temperature changes
6. If there is a power outage during the experiment, there will be a power outage reminder, and it can start running on its own after the power is restored.
7. The ammonia nitrogen analyzer adopts the standard: salicylic acid colorimetric method to complete the measurement of ammonia nitrogen in water quality. Sodium dichloroisothiocyanate, which is standardized by the standard, is used instead of commonly used sodium hypochlorite to greatly enhance the stability and effectiveness of the reagent solution containing chlorine (Type B).
8. The ammonia nitrogen analyzer can produce and store standard colorimetric curves, and adjust the water quality ammonia nitrogen colorimetric curve according to different water objects.
9.Ammonia Nitrogen AnalyzerThe use of an optical path colorimetric system greatly improves the reliability and stability of the instrument.
10. The sample processing method of * can shorten the analysis time (Type B) while ensuring accurate analysis results.
