Air humidity and wind direction conditions, flow data from the sampler

With the implementation of a series of national key engineering projects, the instrument and meter industry is increasingly receiving government attention and support. This will make the market investment value of the instrument and meter industry increasingly prominent. But for the past year, many major events have also occurred in the instrumentation industry. CCTV hosts have independently researched PM2.5, but the data has been questioned& ldquo; Ten Water Strips; A thousand calls before coming out; Overseas acquisition of domestic instrument companies; The dark matter detection satellite developed by Chinese scientists was launched into space; Laboratory safety is crucial, and fire monitors are essential; Frequent meetings related to instruments and meters have been held, and so on. Below, I will take everyone to summarize.

CCTV host Chai Jing's release of "Under the Dome" data has been questioned, and the reliability of relevant testing equipment and data is urgent

In March of this year, Chai Jing, the host who resigned from CCTV, released a deep public welfare survey called "Chai Jing Haze Survey: Under the Dome". In this promotional video, Chai Jing used a large amount of data and materials to support her conclusion. Zhihu's previous netizen's doctoral thesis happened to have some connection with the commission. He looked at it and thought it was a bit incorrect. After checking the materials, he found that almost every data had problems. Firstly, there is a deliberate confusion between haze and PM2. 5. Secondly, there is a lack of testing range and sensitivity data for the sampler, air humidity and wind direction conditions, flow data for the sampler, and the background and time for changing the data aperture to create misleading impressions and tampering with information. This report has made netizens exclaim that it is better to entrust professional matters to professional people!

Next is a series of issues such as data fraud in the air purifier developed by Xiaomi Company, insufficient precision of various environmental detection instruments, and falsification of monitoring data. In the second half of 2015, a total of 8 typical illegal cases were identified by environmental protection departments at all levels, all of which were transferred to public security organs for processing, and 10 responsible individuals were subject to criminal or administrative detention. Starting from January 1, 2016, the Ministry of Environmental Protection implemented the "Measures for Judging and Handling Falsification of Environmental Monitoring Data". According to the Measures, the Ministry of Environmental Protection will conduct special inspections over the next two years to strictly investigate the falsification of local environmental monitoring data, especially air quality testing data. A harsher stick, wielded at counterfeit enterprises, local environmental protection departments, and local governments, is worth praising.
