in some water pollution detection process, in fact, a lot of nitrogen oxide detector applications. Because its nitrogen oxide monitoring is an important way of pollution early warning, pollutant monitoring and treatment effect evaluation, it is necessary to use nitrogen oxide detector for detection, so as to provide and real-time monitoring data. Although everyone is familiar with the nitrogen oxide detector, once asked seriously, many friends are not particularly clear about its detection principle. What is the detection principle of nitrogen oxide detector ? The following is a brief introduction by yi yun Tian:

nitrogen oxide detector detection principle:

The key component of the nitrogen oxide detector is the gas sensor. Gas sensors can be divided into 3 categories in principle:

1. Gas sensors using physical and chemical properties: such as semiconductors (Surface control type, volume control type, surface potential type), catalytic combustion type, solid thermal conductivity type, etc.

2. Gas sensors using physical properties: such as heat conduction, optical interference, infrared absorption, etc.

3. gas sensors using electrochemical properties: such as constant potential electrolysis type, carvani battery type, diaphragm ion electrode type, fixed electrolyte type, etc.

In summary, it is the detection principle of the nitrogen oxide detector. As long as we understand its principle, we can better apply the nitrogen oxide detector, more effectively ensure the effect after detection, truly realize the effective monitoring of nitrogen oxide emissions, and reduce the occurrence of accidents, so as to play a real role in pollution early warning, pollutant monitoring and treatment effect evaluation.
