Background-

The most important corrosive gas in the atmosphere is SO2, which accelerates the corrosion process of most metals.  My country is the largest coal producer and consumer in the world. SO2 pollution is very serious.  In some areas, the SO2 content in the atmosphere exceeds that of the environment. 60% of capacity.  Therefore, for SO2 monitoring we will use accurate and sensitive measurement methods. The main monitoring methods are solution absorption method.  Passive sampling method and online monitoring. Sulphur dioxide sensor can monitor well.

In heavy pollution industries such as power plants and petrochemicals, equipment needs to understand the corrosiveness and changes of its environment during operation.  So as to detect problems in time and take necessary anti-corrosion measures. The pollutants mainly include SO2 and nitrogen oxides. The system has been widely used in thermal power plants, iron and steel plants, cement plants, petrochemical plants and other large coal-burning enterprises.

Flue gas emission continuous monitoring system (CEMS)

We use continuous flue gas emission monitoring system (CEMS) in the continuous monitoring of various industrial waste gas sources, such as thermal power plants, waste incineration plants, coal, petrochemical plants, paper mills and other industries. With the rapid development of industrial production and enterprises, industrial waste gas emission pollution has become a very prominent environmental problem in my country.  According to the "Air Pollution Prevention and Control Law", industrial waste gas will be discharged into the atmosphere after treatment emission. These substances enter the human body through the respiratory tract through different routes, some directly cause harm, and some have an accumulation effect. Which will seriously endanger human health. Industrial waste gas purification is a work that specifically pretreats waste gas generated in factories, workshops and other industrial places.  And then discharges it to meet the national waste gas emission standards. Emit clean and fresh gas

Sulphur dioxide sensor

Sulfur dioxide (SO2) in industrial waste gas is a gas that is relatively harmful to the environment. And a sulfur dioxide sensor is required to measure it. Therefore, the SO2 sensor in the continuous monitoring system of flue gas emission (CEMS).  The industrial mining network recommends the sulfur dioxide sensor. Which can detect 5ppb of SO2 gas.  Which is very suitable for ambient air quality monitoring systems and instruments.

SO2 gas sensor module adopts non dispersive infrared technology, which has the characteristics of high sensitivity, high resolution, oxygen free dependence, stable signal, accurate measurement, low power consumption and long service life.
