According to the national new national economic classification standard, the instrumentation industry has 20 sub-categories, which are generally classified according to application or technology. However, it is sometimes difficult to distinguish between technical classifications and applied classifications. Therefore, the 20 more complicated classifications can be simply classified into 4 categories.

First, scientific test equipment. It is an analysis instrument, a testing machine, an optical instrument, a surveying and mapping instrument and so on. The first type of instrumentation is used on the production line and is connected to the production line. The scientific test equipment is independent. It just takes the samples to the laboratory for testing. Therefore, it is very different from the first category.

Second, industrial automation instrument and control system. This is generally referred to as PA, FA.PA in foreign countries, and the FA is called factory automation. Instrumentation and control systems used in process automation and factory automation fall into this category, and some parts of analytical instruments and electrical instrumentation also fall into this category.

Third, special instrumentation. This category is actually dedicated to a certain area. For example, the instruments used in automobiles and motorcycles will rise quickly. There will be automobile meters, motorcycle meters, etc., and as such, it can also be extended to such fields as agriculture, forestry, animal husbandry, fishery, etc. Fourth, commonly used instrumentation. This mainly refers to supply instruments and other general-purpose instruments. The national standard for application instrumentation was only brought out two years ago. We also have a lot of contacts on weekdays, such as household electric meters and gas meters. There are also some commonly used we have also drawn it out into this category, like scales, medical instruments, timing instruments and some commonly used optical instruments.
