Domestic equipment when self-improvement

As China's atmospheric PM2.5 and atmospheric pollution monitoring equipment technology started late, most of the monitoring equipment is almost completely dependent on imports. Some independently developed instruments and equipment have not yet been studied for key technologies such as engineering, standardization, technology, and networking. Equipment is difficult to meet the needs of the country's large-scale network deployment.

At present, in addition to individual samplers, domestic particulate monitoring equipment relies on foreign products or foreign patents, which to a certain extent has formed a monopolistic situation for foreign equipment manufacturers. From the point of view of procurement of PM2.5 monitoring equipment throughout the country, from the analysis of technical requirements and location distribution, foreign manufacturers have great advantages. According to the survey conducted by reporters, foreign manufacturers have basically occupied more than 60% of the market share this year. At this stage, domestic manufacturers will mainly be in a follow-up position.

In response, Chai Fahe, deputy dean of the Chinese Academy of Environmental Sciences, said that foreign equipment has been dumped to the domestic market. If all (or most) foreign equipment is used, it will face certain risks. Over-reliance on imported equipment and equipment has adversely affected the formation of a controlled monitoring system with independent intellectual property rights in China. Over-reliance on foreign instruments will lead to a cold domestic equipment market, seriously restricting the development of local instruments, and will continue to be hampered by foreign equipment manufacturers in future equipment maintenance, parts replacement, and personnel training.

In the face of powerful international competitors, domestic manufacturers also need to strengthen their own R&D capabilities and cooperate with research institutes to conduct product R&D, upgrades, assessments, and inspections. They also need the support of the state and the government.
