The use principle and function characteristics of ammonia nitrogen detector are that many new people do not know the knowledge points. In fact, ammonia nitrogen detection is particularly important in environmental monitoring. Under certain conditions, ammonia nitrogen in water can be converted into nitrite. If drinking for a long time, nitrite in water will combine with protein to form nitrosamine, which is a strong carcinogen and extremely harmful to human health. Therefore, it is necessary to monitor the ammonia nitrogen composition. The appearance of ammonia nitrogen detector facilitates the monitoring of ammonia nitrogen composition. Let's talk about the use principle and drinking function characteristics of ammonia nitrogen detector.
In fact, the method of how to determine wastewater by total phosphorus analyzer is very simple. There are two parts in the total phosphorus test module. The first part is the high temperature chemical digestion module, which is used to heat digestion samples, and the second part is the analysis module, which is used to test the concentration of phosphate. Here is a detailed explanation.
How to use the BOD tester is a question that we will have when we first use the instrument.
