Instruments and meters are a means and equipment for people to measure, collect, analyze and control various kinds of information in the objective world. Instruments and meters are the basic tools to understand and change the world, and are also the source and component of the information industry. With the continuous transformation and upgrading of China's traditional industries, the accelerated development of emerging industries, and the continuous improvement of people's living standards, the demand for instruments and meters for major projects, industrial equipment, intelligent manufacturing, life medicine, new energy, marine engineering, nuclear power, and science will further expand, and China's instrument and meter industry will usher in new development opportunities.

Since 2011, the number of units in China's instrument manufacturing industry has increased. The data shows that by 2020, China's instrument manufacturing enterprises will reach 4906, an increase of 455 compared with 2019. From January 2021 to February 2021, China's instrument manufacturing enterprises will reach 5333

Instruments and meters are equipment or devices used to check, measure, control, analyze, calculate and display the physical quantity, chemical quantity, biomass, electrical parameter, geometric quantity and motion state of the measured object. According to the industry classification, the instrument industry includes 20 small specialties, including industrial automatic control system equipment, electrical instruments, optical instruments, laboratory instruments, analytical instruments, measuring machines, industrial instruments and special instruments for environmental monitoring..

The instrument is widely used in steel, petroleum, chemical, aerospace, automobile and other industries. It is the "multiplier" of industrial production, the "pioneer" of scientific research, the "combat effectiveness" of military affairs and the "combat effectiveness" of modern life. The "material judge" is the key and core of the "Made in China" method in "Intelligent Manufacturing in China", and also the cornerstone of building a strong country in science and technology in the world. As a means of measurement and testing, instruments and meters are an important link to improve the level of measurement and testing in China
