I. What parameters can Voc online monitor measure? Volatile organic compounds are any carbon compounds that participate in photochemical reactions in the atmosphere other than CO, CO2, H2CO3, metal carbide, metal carbonate and ammonium carbonate. At the chemical level, the main components of the vocs are hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, mainly: BTEX compunds, organochlorines, fluoride series, organoketone, ammonium, alcohol, ethers, esters, acids and petroleum hydrocarbons. Product description: The M-2060 fixed source TVOC Online Warning Monitoring System (PID) consists of a sampling subsystem, a pre-treatment subsystem, a gaseous contaminant (TVOC) monitoring subsystem and a data acquisition and treatment subsystem, a pneumatic pre-treatment system de-watering, re-performing photoion detector (PID) measurement analysis, after analysis

　　I. Portable infrared CO/CO2 analyzer Summary This instrument meets the national standards of the non-dispersible infrared law of GB/T18204.2-2014, Part 2 of Health Testing Methods in Public Places: Chemical Contaminants, GBZ/T300.37-2017, Part 37 of Air Toxic Substances Detection at Workplace: Carbon Monoxide and Carbon Dioxide, and GB/T9801-1988 Air Quality Carbon Monoxide. This instrument meets the national measurement control protocol of JJG635-2011 " Carbon Monoxide, Carbon dioxide Infrared Gas Analyst " , and the main technical indicators meet the technical requirements of the national secondary instrument and obtain a certificate of validation from the Chinese Academy of Measurement Sciences (confirmation: the instrument meets the technical requirements of Level II). This instrument has built-in zero filters, six valves to switch zero to measurements.

Frozen gas analyzers are equipment for measuring the flue content of CO2, CO, NOx, SO2, etc., using continuous analysis of electrochemical sensors. This is mainly for small-scale fuel, gas boiler pollution emissions or environmental monitoring near the source of pollution, and we, Highpower Environmental Technology, Ltd., will show you the 2021 flue gas analyzer sample.

It is well known that the VOC gas detector is an instrument used to continuously measure toxic and harmful organic gases in hazardous or industrial environments, especially for personal safety protection and on-site VOC detection, and therefore it is highly demanding for data collection. If the data are not collected correctly, it is likely that the effects of the later use will be directly affected. So you know how the VOC gas detector works? If you don't know, let's see how we use it!

In recent years, as the economy has evolved and industry has progressed, incidents of indiscriminate discharge of nitrogen-containing sewage have also continued. In the water, ammonia nitrogen originates mainly from household sewage, industrial wastewater, and agricultural drainage. Ammonia Nitrogen has many sources of pollution, large emissions and high concentrations of discharges, and the over-standard ammonia Nitrogen sewage discharge to the water body causes black smelt, increases the difficulty and cost of sewage treatment, and even has toxic effects on the population and the natural environment, causing great harm. What is ammonia nitrogen? Ammonia Nitrogen means nitrogen in the form of free ammonia (NH₃) and ammonium ion (NH₄ +) in water. Nitrogen is present in a variety of forms in wastewater, including organic nitrogen, ammonia nitrogen (NH₄ +-N), nitrogen nitrate (NO₃ -N) and nitrogen nitrous (NO₂ -N), of which ammonia is the predominant form of presence

Most importantly, the Hong Kong Joao Bridge is officially shuttled. Moreover, look at how this bridge, crowned as “one of the most demanding environmental projects in our history of transport”, has served as a model for marine development and environmental protection. For three full hours and 30 minutes, this means the Hong Kong Joao Bridge, which is officially open at 9 a.m. on 24 October 2018. The 55-km-long bridge, the island and the one-size-fits-all road, which runs through Pearl Sea, Hong Kong and Macao, reduces the journey time directly to one sixth of the original, to the world's attention. First of all, we need Cope to see how big the bridge is. One of China ' s most technically complex projects, construction requirements and standards in the history of transport are the anti-typhoon class 16 and the earthquake class 8, which is known to last 120 years.
