With the development of science and technology, the country's requirements for construction quality are becoming more and more strict. Therefore, in recent years, a large number of new detection methods and corresponding detection instruments have emerged. For example, stress testing pile foundation, road surface roughness testing, etc., these instruments have more potential for further development and production, the profit content is also much larger than the regular stereotypes. As for the field of conventional measuring instruments, such as the application of the most common mercury sphygmomanometer, mechanical scales and case scales, to replace the product of electronic sphygmomanometer, electronic platform scales have not yet been popularized. Product price, quality and service are the key. China should be fully capable of establishing large-scale specialized companies to create advanced, environmentally-friendly and low-cost electronic products. China's metrology industry, pressure instruments and meters for many years using piston pressure gauge, artificial addition and subtraction code, we should be able to develop an automatic coding equipment, and its industrialization. With the trend of residential commercialization, China's card meter, meter, gas meter, heating meter and even the home phone meter (for the title) and other instruments have great market potential, who call group business Birth, high-quality low-cost products available. The recent decade of nanotechnology and its micromachining has shown us a new area of ​​development that combines integrated circuits, micromachining, and nano-metrology into a revolution that could have a revolutionary impact on the instrumentation industry. To sum up, it is suggested that in formulating the industrial policy and development plan of instrumentation industry, the state should continue to nurture a handful of important, promising and effective key enterprises. Enterprises that are heavily indebted and have no marketable products should be determined Off, stop, and, turn, can not protect backward.
