Integrative flue oxygen analyzer can be widely applied in department of electronic power, metallurgy, heating, building material and electron, etc to analyze the oxygen content in flue gas from industrial boiler and furnace. It can also be used in monitoring and analyzing the oxygen concentration in the combustion gas from large or small-scale boiler, industrial boiler and combustion devices to achieve the purposes of reasonable combustion for low oxygen content, lowering the combustion consumption and loss, stabilizing techniques, improving the products quality and reducing environment pollution, etc.
Integrative flue oxygen analyzer main features:
1.Making microprocessor as the core is with good stability, high reliability and long calibration cycle for features, etc;
2.The auto-compensation system for temperature could eliminate the influence from environment temperature.
3.The measurement range can be expanded to 0 ~ 40.00％O2 (oxygen-enriched combustion) with the measurement range shifting automatically;
4.Users can set the upper and lower limits of oxygen concentration related to 4-20mA output to get the analog output with higher accuracy;
5.One-way or two-way communication with the computer can be accomplished through the communication port;
6.The advanced calibration function allow users to calibrate online.
