Model ATS-202A is single of Multigas Portable Instrument for Bio Gas and process gas Analysis for various industries. Landfill gas and Bio gas is produced by the bio-degradation of waste. Landfill gas is produced from general waste buried in the ground; and bio-gas from plant and animal waste products contained in a sealed digester tank.
Both gases comprise mainly methane (CH4) and carbon dioxide (CO2). The methane component is either burnt as a fuel or flared off as waste.
Our landfill gas / Bio gas analysers maximise the extraction of energy and ensure it is safe to burn without explosion - (the explosion problem occurs if air, i.e. oxygen, infiltrates the gas).
Our Application specific Portable Gas Analyzers provides continuous process analysis of the following Gases.
Oxygen (O2), Carbon Monoxide (CO),  Carbon dioxide (CO2), Sulphur Dioxide (SO2), Nitric Oxide (NO),Nitrogen Dioxide (NO2), Nitrous Oxide(N2O), Hydrogen (H2), Hydrogen Sulphide ( H2S) and Hydrocarbons.
