As we all know, nitrogen oxides refer to compounds composed of only two elements of nitrogen and oxygen. In order to better detect the concentration of nitrogen oxides generated by the on-site operating environment, according to the national regulations on the allowable concentration of nitrogen oxides, it is necessary to use a nitrogen oxide detector to detect the concentration of nitrogen oxides in real time on-line, so as to avoid the concentration of nitrogen oxides exceeding the harm to human body. So what's the use of NOx detector ? The following is a brief introduction by yi yun Tian:

nitrogen oxide detector is the 1 instrument used to detect nitrogen oxide gas leakage or concentration. it can choose and match different parameters according to the same environment, at present, there are two kinds of physical methods or electrochemical methods on the market. The electrochemical principle is to use a gas sensor to detect the nitrogen oxide gas in the environment, and convert the current signal into readable data and can be output or edited.

The nitrogen oxide detector can effectively monitor nitrogen oxide emissions, thereby reducing accidents. Nitrogen oxides, mainly nitric oxide and nitrogen dioxide, are an important cause of photochemical smog and acid rain. Toxic smog formed by the reaction of nitrogen oxides and nitrogen hydrogen compounds in automobile exhaust by ultraviolet radiation is called photochemical smog. Photochemical smog has a special odor, irritates the eyes, harms plants, and can reduce atmospheric visibility. Nitric acid and nitrous acid produced by the reaction of nitrogen oxides with water in the air are components of acid rain.Nitrogen oxides in the atmosphere are mainly derived from the combustion of fossil fuels and the burning of plants, as well as the transformation of nitrogen-containing compounds in agricultural soil and animal excreta.

Nitrogen oxide monitoring is an important way for pollution early warning, pollutant monitoring and treatment effect evaluation. Nitrogen oxide detectors are required to provide accurate and real-time monitoring data. Therefore, currently in petroleum and petrochemical, chemical plants, smelters, iron and steel plants, coal plants, thermal power plants, water plants, pharmaceutical workshops, tobacco companies, atmospheric environmental monitoring, scientific research institutions, building construction, fire alarm, sewage treatment, industrial process control, Boiler room, garbage treatment plant, underground tunnel, oil pipeline, gas station, underground pipe network maintenance, indoor air quality testing, food processing, sterilization, refrigeration warehouse, pesticide fertilizer, pesticide production and other fields, all need to be applied to the nitrogen oxide detector.
