There are two kinds of measurement methods for ammonia nitrogen analyzer measurement. One is the colorimeter method and the other is the electrode method. The principle of colorimetry is that ammonia nitrogen will produce a stable change with the reagent in water. This change is proportional to the sample concentration. The electrode method is to measure the initial potential value of the sample first, then add a certain concentration of standard solution and then measure the potential of the mixed solution. The value is calculated from the difference between two measurements.
Ammonia analyzers have independent piping and can be used for high-precision measurement. The structure is simple and clear. The maintenance cost is low and it is different from other instruments. The on-line ammonia nitrogen analyzer can be used without first calibration. And can get stable and accurate results. The instrument has its own data storage capability, which facilitates the experimenter's statistical analysis. Some ammonia nitrogen analyzers can also be remotely controlled.
Ammonia analyzer technology advantages:
1, can dilute the high concentration sample
2, can be automatically controlled for a long time, do not need experimental staff next to improve the efficiency of experimental staff, and support long standby mode
3, reducing the consumption of reagents, pharmaceuticals, detection time is generally only a few minutes to more than 10 minutes
4. The electronic system is completely isolated from the power part to ensure the safety of the instrument.
5, the working environment temperature range: 0 °C ~ 40 °C, if the winter and summer labs must open the air conditioning, ammonia nitrogen analyzer is sensitive to temperature changes
6. If the power is cut off during the experiment, there will be a power off reminder. After the call, you can start the operation on your own.
7. The ammonia nitrogen analyzer adopts the national standard: the salicylic acid colorimetric method completes the water quality ammonia nitrogen measurement, uses the sodium dichloroisocyanate regulated by the international standard to replace the commonly used sodium hypochlorite, so that the chlorine stability and effectiveness of the reagent solution are greatly enhanced. (Type B).
8. The ammonia nitrogen analyzer can be used for the preparation and storage of standard colorimetric curves, and for the adjustment of the ammonia-nitrogen colorimetric curve of the water according to different water body objects.
9. The ammonia nitrogen analyzer uses a unique light path colorimetric system, which makes the instrument reliable and stable.
10. The unique sample processing method shortens the analysis time (Type B) on the premise of accurate analysis results.
