Instruments and meters have a wide range of applications, covering various aspects such as industry, agriculture, transportation, technology, environmental protection, national defense, culture, education, health, and people's lives. They play the role of gatekeepers and guides in the operation of various industries in the national economic construction. Due to its special status and significant role, it has a huge multiplier and driving effect on the national economy, with good market demand and enormous development potential.

（1） The specific demand objects and coverage scope of the instrumentation industry market can be expressed from the following aspects:
Against the backdrop of human society entering the knowledge economy era and rapid development of information technology, instruments and their measurement and control technologies have been increasingly widely applied, providing a good opportunity for the rapid development of the instrument industry. Instrumentation is the source and component of the information industry, and an important foundation of information technology. Academician Qian Xuesen has the following discussion on the new technological revolution: 'The key technology of the new technological revolution is information technology, which consists of three parts: measurement technology, computer technology, and communication technology. Measurement technology is the key and foundation.'. The information technology production industry is also classified as three industries: computer, communication, and instrumentation.
2. Instruments and meters are widely used for measuring and controlling the process flow of equipment and transforming traditional industries. They are an important component of modern large-scale key complete sets of equipment and an important link for information technology to drive industrialization. According to relevant information, with the improvement of equipment level, the proportion of instruments and meters in the total investment of engineering equipment has reached about 18%; One third of the investment in modern Baosteel technology and equipment is used to purchase instruments and self-control systems.
The rapid development of high-level scientific research and high-tech industries has increased the demand for instruments and meters. Instruments and meters are playing a very important role in the implementation of science and education, knowledge innovation, and technological innovation. High level scientific experiments cannot be separated from scientific instruments, and the progress of modern science increasingly relies on the development of instruments. The development of modern biology, medicine, ecological environment protection, new materials (nanomaterials, etc.), and modern agriculture are also based on the development of precision instrument technology.
4. Instruments and meters have become an important component of modern national defense construction technology and equipment. One third of China's fixed assets in the aerospace industry are instruments, meters, and computers; The instrument expenses of carrier rockets account for about half of the total development funds; High precision guidance and control of missiles, precise measurement and infrared imaging in aerospace, and high-temperature experimental equipment are all key products in national defense equipment.
5. Instruments and meters are widely used as important means of implementation and guarantee for industry in exploring sustainable development of human society, resisting natural disasters, governing the country according to law, and implementing relevant laws (such as quality, inspection, measurement, environmental protection, etc.).
