The GIR5500 series analysers are ideal for biogas applications. These gases are usually a mixture of methane (CH4) and carbon dioxide (CO2) together with oxygen (O2) and hydrogen sulphide (H2S) which have implications for efficiency and safety. Two, three or four gas versions are available in a variety of configurations for Zone 2 applications.



Methane and carbon dioxide are both greenhouse gases (GHG). Methane is an important fuel gas for CHP engines, if not used as fuel then it is flared off to produce the less harmful carbon dioxide. Hitech use NDIR sensors to measure methane and carbon dioxide. These are sensors specially designed to withstand the damp, corrosive atmosphere often found in these applications.



Oxygen is an important process indicator in both landfill and digester gas. In landfill gas, a low reading might indicate the presence of an underground landfill fire, whilst a high reading may indicate over extraction from the site. In digester gas, a high reading may indicate a decrease in microbial activity due to poisoning. For this application Hitech use a special long-life electrochemical cell designed for use in the presence of acidic gases, e.g. carbon dioxide.
