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. With the development of science and technology, the appearance of the BOD tester brings us great convenience in environmental testing. This instrument can quickly determine the BOD of water samples. The following brings us the operation and notes of the BOD tester.
COD in water is the basic index of water quality detection. Any industry that needs to discharge sewage outside needs to detect the content of COD in the water, which can only be discharged if it meets the standards, and can only be discharged if it does not meet the standards after treatment. The following is a detailed analysis of five detection methods of COD detector
Shenchanghong's total phosphorus tester (tp-1a / tp-2a / cnp-301 / 301c / D / cnpn-401 / 401 / 401 / D / mulp-8c / pmulp-8, etc.) selects the corresponding total phosphorus test program in the main menu, without re establishing the standard curve, just put the digested total phosphorus reagent test tube into the instrument to read the total phosphorus value expressed in concentration units, and save the record results.
As one of the themes of today's environmental protection industry, portable COD analyzers are attracting more and more attention. It is an instrument for detecting COD content in water. It is a chemical instrument for detecting the COD content in water. The water sample is oxidized by a chemical reagent to produce a specific color. The color is proportional to the concentration of COD. The absorbance of the sample is detected by spectrophotometry, and the data is processed by microcomputer technology. Directly shows the COD content value.
