The Single Channel In-situ Probe type Flue Gas Analyzer- GCEM 1000 is an accurate, reliable In-situ flue gas analyzer that measures gases by Infrared absorption Gas Filter Correlation [GFX] technology. The GCEM1000 measuring probe is mounted on the stack/duct and uses an intrusive stainless steel measurement chamber equipped with sintered diffuser to allow flue gas excluding particulate into the measurement chamber. In case of Single Channel In-situ Probe type Flue Gas Analyzer, the infra red beam from transceiver unit passes through the probe measurement and is reflected back to the Infrared detector mounted within the transceiver unit through a gold-coated mirror. This Single Channel In-situ Probe type Flue Gas Analyzer allows analyzer calibration to be verified quickly and easily by the injection of zero and span gases.
