Description Overview GAOTek hydrogen sulfide analyzer in the production of biogas several gases occur. Biogas is the gaseous emissions from anaerobic degradation of organic matter (from plants or animals) by a consortium of bacteria. Biogas is principally a mixture of methane (CH4) and carbon dioxide (CO2) along with other trace gases, such as Hydrogen sulfide (H2S) and Oxygen (o2) gas, They are dangerous, toxic, combustible. A biogas analyzer is necessary and important.
