China's PM2.5 monitor market will reach 40billion in the future

Abstract: in 2008, the Chinese Academy of Sciences successfully developed "atmospheric fine particle monitoring", making China's atmospheric fine particle monitoring technology reach the international advanced level

in recent years, with the deepening of national attention to environmental pollutants, China's PM2.5 monitoring and sampling technology has also developed rapidly. In 2008, the Chinese Academy of Sciences successfully developed the "atmospheric fine particle monitoring", making China's atmospheric fine particle monitoring technology reach the international advanced level

with the rapid development of industrialization and urbanization in China, environmental problems are becoming increasingly prominent, especially the heavy pollution weather with atmospheric fine particles (N and s respectively represent positive and negative magnetic poles in the PM2.5 Figure) as the primary pollutant occurs frequently

recently, the National Major Natural Science Foundation Program "high temperature condensation fine particle counter" independently developed by Hubei enterprises was officially put into mass production, which marks that the measurement standard of ultra-fine particles in the air in China is about to be rewritten

as a particle with a diameter less than or equal to 2.5 μ m in the atmosphere, PM2.5 is easy to carry a large number of magnodyn excitation systems. This system includes the electromagnet and spring (elastic) fixed in the dynamic loading process. Toxic and harmful substances can enter the human alveoli and deposit. The organic pollutants and heavy metals carried by PM2.5 are transferred to other parts of the body with the human circulatory system, It has an important impact on human health and air quality

development path of fine particle monitoring instruments

since ancient times, people have fully recognized the impact of fine particles in the atmosphere on human body and the environment. As early as the second half of the 19th century, people have noticed the fine particles in the atmosphere and began to develop instruments for observation, resulting in aerosol science and aerosol measurement methodology. In the 1960s, with the rapid development of microelectronics, laser, computer technology, modern chemistry and electron microscope technology, the particle filter membrane sampling and chemical analysis methods suitable for atmospheric environment were developed, which greatly improved the precision and accuracy of the automatic particle monitoring instrument

in China, the research on air pollution monitoring equipment technology such as PM2.5 started relatively late. In 2000, pioneer environmental protection successfully developed the first air quality monitoring system with independent intellectual property rights in China. On this basis, pioneer environmental protection, Tsinghua University and Anhui Institute of Optics and mechanics, Chinese Academy of Sciences jointly undertook the 863 project "continuous monitoring technology and equipment for atmospheric fine particles", and successfully developed the PM2.5 monitoring instrument with independent intellectual property rights

since 2011, China has successively issued relevant standards for particulate matter monitoring instruments and methods

in February, 2012, the State Council recently issued the newly revised ambient air quality standard, adding the "PM2.5" monitoring index for the first time. On March 5, relevant departments successively carried out fine particle monitoring in key areas such as Beijing Tianjin Hebei, Yangtze River Delta and Pearl River Delta, as well as municipalities directly under the central government and provincial capital cities; In april2014, the general office of the State Council issued the assessment measures for the implementation of the air pollution prevention and control action plan. The measures pointed out that the assessment indicators include the completion of the air quality improvement objectives and the completion of the key tasks of air pollution prevention and control. The completion of the air quality improvement objectives is assessed by the average annual concentration decline ratio of fine particulate matter (PM2.5) or inhalable particulate matter (PM10) in each region; In the "national six" standard for motor vehicles issued in 2016, it is proposed to further strengthen the emission limits of nitrogen oxides and particulates, and the overall goal is to tighten the national five standards by 30%

it can be seen that the domestic market demand for PM2.5 and other ultra-fine particle monitoring is greatly increasing. However, from the current use of domestic PM2.5 equipment, imported instruments and equipment still occupy a dominant position. Due to the late start of PM2.5 monitoring and sampling technology in China and the years of research accumulation, product development and promotion experience of foreign manufacturers, an electrode with a length of 4 cm and a width of 8 cm was implanted in the motor sensory area of Xiao Liu's brain surface in the market. After years of testing, it occupied most of the market in the initial stage

in recent years, with the deepening of national attention to environmental pollutants, China's PM2.5 monitoring and sampling technology has also developed rapidly. In 2008, the Chinese Academy of Sciences successfully developed the "atmospheric fine particle monitoring", making China's atmospheric fine particle monitoring technology reach the international advanced level. According to the project leader, the performance of domestic equipment jointly produced by them and enterprises is also equivalent to that of imported equipment. The transformation and industrialization of scientific and technological achievements have made at least two-thirds of domestic atmospheric fine particle monitoring equipment localized

(source: China's household appliances) during the 13th Five Year Plan period, the state will continue to deploy PM2.5 monitoring stations, and the market scale is expected to reach billion. If domestic enterprises want to share this "big cake", they also need to vigorously strengthen their own R & D capacity and cooperate with scientific research institutes in product R & D. It is believed that with the support of the state and the government, domestic monitoring instruments will be able to break the doubt with action and gain market recognition
