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

With the implementation of a series of key national projects, the instrument and meter industry has increasingly received attention and support from the government. This will make the market investment value of the instrument and meter industry increasingly prominent. However, in the past year, quite a few major events have occurred in the instrumentation industry. A CCTV host conducted self-funded research on PM2.5, but the data was questioned. The "Water Pollution Prevention and Control Action Plan" has finally been released after much anticipation. Domestic instrument companies' overseas acquisitions; The dark matter detection satellite developed by Chinese scientists was launched into space. Laboratory safety is of great importance, and fire monitors are indispensable. Meetings related to instruments and meters are held frequently, etc. Now, I will summarize them together with you all.
The data released by CCTV host Chai Jing for "Under the Dome" has been questioned, and the reliability of the related testing equipment and data is extremely urgent
In March this year, Chai Jing, a former CCTV host, released a deep public welfare investigation titled "Chai Jing's Smog Investigation: Under the Dome". In this promotional video, Chai Jing used a large amount of data and materials to support her conclusion. A netizen's doctoral dissertation on Zhihu happened to be somewhat related to emission. He felt something was amiss at first glance and, after checking the materials, found that almost every piece of data was problematic. First, there is an intentional confusion between smog and PM2.5. Secondly, there is a lack of data on the testing range and sensitivity of the sampling instrument, air humidity and wind direction conditions, flow rate data of the sampling instrument, as well as the background and time for misleading impressions and data tampering caused by changing the data scope. This report came out, which made netizens cry out: "Let professionals handle professional matters!"
The following are a series of issues such as data falsification of air purifiers developed by Xiaomi Corporation, insufficiently precise environmental detection instruments and meters, and data falsification in monitoring. In the second half of 2015, environmental protection departments at all levels verified a total of 8 typical cases of violations. All of them have been transferred to the public security organs for handling, and 10 responsible persons have been criminally or administratively detained. Starting from January 1, 2016, the Ministry of Environmental Protection has implemented the "Measures for the Determination and Handling of False Environmental Monitoring Data". According to the provisions of the Measures, the Ministry of Environmental Protection will carry out special inspections over the next two years to strictly investigate the falsification of local environmental monitoring data, especially air quality testing data. It is commendable that a harsher stick has been swung at counterfeiting enterprises, local environmental protection departments and local governments.
