The GIR5000 series analysers are ideal for biogas applications, with two or three gas versions available in a variety of configurations; all of which are ATEX certified. Hitech use NDIR sensors to measure methane and carbon dioxide, and are 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, and for these applications Hitech use a special electrochemical cell designed for use in the presence of acidic gases e.g. carbon dioxide.
Hydrogen sulphide is present in landfill and digester gas in varying amounts depending on the substrate composition. Hitech have developed a system which allows for continuous measurement of H2S. At 2000ppm H2S.
Hitech provide internal filters, an internal pump and low-flow alarm as standard. An external coalescing filter is highly recommended and cooling options can also be offered to remove water. The enclosure itself contains a small heater to ensure that water vapour does not condense in the analyser.
Hitech are ready to recommend complete systems on receipt of full gas stream specifications.
