Ammonia nitrogen analyzer is mainly used to analyze the concentration of nitrogen in samples, and in some cases, it can also detect the concentration of ammonia. There are two measurement methods for it, 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.
Online ammonia nitrogen analyzers are equipped with independent pipelines for high-precision measurement, and have a simple and clear structure 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 analyzers can also be remotely controlled.
Characteristics of ammonia nitrogen analyzer:
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, this 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.
