Instrumentation has a wide range of applications, covering industries, agriculture, transportation, science and technology, environmental protection, national defense, culture, education, sanitation, and people's lives. It also assumes the tasks of gatekeepers and mentors in the operation of all sectors of national economic construction. Due to its special status and large role, it has a huge multiplier and pull for the national economy, and has a good market demand and great potential for development. Specific requirements can be expressed in the following aspects:

1. In the era of human society entering the era of knowledge economy and the rapid development of information technology, instrumentation and its measurement and control technologies are increasingly used, providing a good opportunity for rapid development of the instrumentation industry. Instrumentation is the source and component of the information industry and an important basis for information technology. Academician Qian Xuesen described the new technology revolution as follows: “The key technology of the new technology revolution is information technology. Information technology is a measurement technology, computer technology, and communication technology. Measurement technology is the key and foundation.” The technology production industry is characterized by three industries: computer, communications, and instrumentation.

2. Instruments and meters are widely used in the measurement and control of equipment processes and transformation of traditional industries. They are an important part of modern large-scale key equipment and an important link for informatization to drive industrialization. According to the relevant data, with the improvement of equipment level, the proportion of instruments and meters in the total investment in engineering equipment has reached about 18%; in the modern Baosteel technology and equipment investment, one-third of the funds are used to purchase instruments and automatic control systems.

3. The development of high-level scientific research and high-tech industries has rapidly increased the demand for instrumentation. Instruments and meters are playing a very important role in the process of rejuvenating the country through science and education, knowledge innovation, and technological innovation. Various high-level scientific experiments cannot leave scientific instruments, and the progress of modern science also increasingly depends on the development of cutting-edge instruments. Modern biology, medicine, eco-environment protection, new materials (nano-materials, etc.), development of modern agriculture, etc. are also based on the development of cutting-edge precision instrument technology.

4. Instruments and meters have become an important part of modern national defense construction technology and equipment. One-third of the fixed assets of China's aerospace industry are instrumentation and computers; the expenditure of the instruments for launch vehicles accounts for about 1/2 of the total research funding; the precision of missiles is high. Guidance, control, aerospace fineness measurement and infrared imaging, and special high-temperature experimental equipment are all key products in defense equipment.

5. Instrumentation and instrumentation are widely used as an important means of implementation and safeguarding industry in the process of exploring the sustainable development of human society, resisting natural disasters, governing the country according to law, and implementing relevant laws (quality, commodity inspection, measurement, environmental protection, etc.).
