As industrial development proceeds rapidly, more and more gases are released into the air, and many of them have an impact on human life. General factories in the production process not only need to have the purity of industrial gases as raw materials, but also in the production process will produce a variety of high purity derivative harmful, toxic gases, these gases often have a certain degree of harm, and therefore to have a variety of high-sensitivity, high accuracy, high-performance gas detection instruments to monitor, to prevent industrial gas raw material leakage or derivative gas exceeds the standard, always monitor, reduce the hidden danger.

Some of the disasters were caused by flammable gas leaks at the company. A leak of vinyl chloride gas was not detected in time, resulting in a large amount of vinyl chloride combined with air to form an explosive mixture that permeated the vicinity of the company's plant. The nearby area also happened to have a large number of large trucks carrying coal chemicals, resulting in a gas explosion that detonated the large trucks and passing vehicles waiting to be unloaded, causing significant casualties, which was really distressing.

The importance of real-time monitoring gas detectors: Therefore, according to the relevant regulations, chemical companies should place fixed gas monitoring equipment in the plant, which is used to detect harmful gases that may leak, and should arrange for relevant technical personnel to conduct inter-area testing of the plant to prevent problems with fixed equipment or the phenomenon of blind detection areas.

Some accidents in the flammable gas leak after the plant actually did not receive the first alarm and found, which is obviously not in accordance with the provisions of the relevant gas detection or supervision caused by the plant. Industrial gas detectors have a very important role in the production of industrial enterprises, is the key to eliminate accidents and ensure the smooth production of enterprise safety, is the production of personnel and the safety of the surrounding public protection.
