The GCEM 4000 series Insitu gas analyzer is manufactured by Codel lnternational Ltd. UK who are specialized in the design and manufacture of High Technology Instrumentation for Combustion Processes and Atmospheric Pollution Emissions. The GCEM 4000 series Insitu gas analyser is an accurate, reliable Insitu flue gas analyser that measures gases by infrared absorption gas filter correlation (GFX) technology. It is capable of continuously measuring upto seven gases at a time. The GCEM 4000 series measuring probe is mounted on the stack / duct and uses an intrusive stainless steel measurement chamber equipped with sintered diffuser filter to allow flue gas excluding particulate into the measurement chamber. The probe incorporates a 1 m long measurement cell, into which the gas diffuses through an array of sintered filters. Infrared beam from transceiver unit passes through the probe measurement chamber and is reflected back to the infrared detector mounted within the transceiver unit through a gold coated mirror. Analyser utilizing an Insitu probe arrangement allows analyser calibration to be verified quickly and easily by the injection of zero and span gases. Fully automated zero calibration using compressed air provides long-term accuracy with minimal maintenance. For online normalization, GCEM 4000 series gas analyser can be offered with built in measurement of H O, CO , ² ² temperature and pressure parameters.
