Landfill gas monitor
Landfill gas monitor
A landfill gas monitor is mainly used to detect landfill gas, in addition to methane CH4 and carbon dioxide CO2 gases produced by microbial decomposition in the landfill, it can also detect oxygen O2, hydrogen sulfide H2S, ammonia NH3, volatile organic compounds (VOC), and mercaptan and sulfuric acid (TSA) and other malodorous gases.
What is landfill gas?
Landfill gas is a mixture of methane and carbon dioxide as the main components produced by microbial decomposition of domestic waste after landfilling in the landfill, LFG is the acronym for landfill gas. Depending on the source and composition of the landfill waste, landfill gas contains 30% to 55% methane by volume and 30% to 45% carbon dioxide by volume, in addition to small amounts of air, malodorous gases, and other trace gases.
Methane in landfill gas is a flammable and explosive gas. Since methane needs to be mixed with air and accounts for 5 to 15 percent of the air before it explodes, there is little danger of explosion in a closed landfill. However, when landfill gas is transferred outside the landfill through soil voids and mixed with air, an explosion may occur. Landfill gas also contains traces of ammonia, carbon monoxide, hydrogen sulfide, and a variety of volatile organic compounds (VOCs), which can create odor problems and air pollution. The two main components of landfill gas (methane and carbon dioxide) are both greenhouse gases. However, according to the United Nations Intergovernmental Panel on Climate Change (IPCC), carbon dioxide in untreated landfill gas is the result of the decomposition of biomass, which is part of the natural carbon cycle and is not counted as a greenhouse gas. Methane from landfill gas is included in the list of atmospheric greenhouse gases, and its greenhouse effect is 21 times greater than that of carbon dioxide in the same volume.
Fosensor Landfill gas monitor
Fosensor has specially developed and produced Landfill gas monitors for landfills. This LFG landfill gas monitor monitors the landfill gas through the built-in Odor detection sensor, and can simultaneously monitor nine indicators (ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, methyl sulfide ether, dimethyl disulfide, carbon disulfide, styrene, odor) specified by the “Emission Standard for Odorous Pollutants (GB14554-1993),” which include the control of malodorous substances including odor. Nine kinds of indicators (ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, styrene, odor) can be monitored at the same time, and optional additional PM2.5, PM10, temperature, humidity, wind speed, wind direction, atmospheric pressure, illuminance, noise, and other parameters and indicators.
Above is the introduction of the Landfill gas monitor, LFG landfill gas detector is not only applied to landfills, but also widely used in sewage treatment plants, pharmaceutical plants, oil refineries, chemical plants, slaughterhouses, breeding factories, feed processing plants, paper mills, printing factories, plastics recycling factories, laboratories, and all other occasions that need to detect the concentration of gas.
Greenhouse gas emissions monitoring
Greenhouse gases are gases that have a long-term impact on the Earth's climate. They include carbon dioxide, methane, nitrogen oxides, and freon.
Natural gas monitor is a device used to detect and monitor natural gas, and its main functions are as follows:

Applications of temperature sensors in industries
Temperature sensors are common sensors used to measure and detect changes in temperature to obtain subtle changes in temperature, as well as patterns and ranges of temperature changes and many other parameters.

How to monitor air quality in the workplace?
In modern office environments, there are many sources of pollution, including ozone and hydrocarbons generated by office equipment (printers, etc.), formaldehyde, ammonia, benzene, VOC
Ozone gas monitor principle and application
Ozone gas monitor mainly detects the concentration of ozone in the air to assess the level of ozone pollution in the environment.
