Fuji Electric, Gas analyzers Oxygen Analyzer

This oxygen analyzer is used to continuously measure oxygen concentration in combustion exhaust gas of industrial boilers or furnaces, and is ideally suited for combustion management and control. The analyzer system is comprised of the detector and converter coupled together as a complete system. Detector setting configuration includes the detector flow guide tube and detector sensor. The flow guide tube is inserted directly into the gas and directs gas to the sensor for measurement. The converter (ZKM) is comprised of the signal processor, input/ output and communications, display and system controls. The converter is equipped with advanced functionality such as performing the sensor diagnostics and sensor recovery function, so the detector can be used within long term stability.

Converters (transmitters):

ZKM1 (IP66) ZKM2 (IP67)



ZFK8 with flow guide tube

ZTA (up to 1500 ° С)
