2. The environmental monitoring system and industrial process analysis system mainly include: continuous emission monitoring system for flue gas, automatic monitoring system for ambient air quality, analysis system for building materials, chemical process analysis system, air separation process analysis system, metallurgical process analysis system and petrochemical process analysis system.

3, environmental protection operation and maintenance services include: online pollution source monitoring system operation and maintenance services and environmental air quality monitoring system operation and maintenance services.

Analytical instruments are widely used in modern industry. Analytical instruments are widely used in the national economic foundations and pillar industries such as metallurgy, petrochemicals, electric power, building materials, and environmental protection that require continuous production. The proportion of investment in modern industrial engineering equipment is increasing day by day. For most analytical instruments, end customers will typically replace it within 5-8 years.

Environmental protection is a basic national policy of China. However, due to the weak foundation of environmental management in China, environmental monitoring instruments that are the basis of environmental protection cannot fully meet the needs of development, and there is ample room for development. In 2008, the output value of China's environmental monitoring system was 7.734 billion yuan, and it reached 11 billion yuan in 2010, maintaining an annual growth rate of nearly 20%.
