Oxygen measurement
Fields of application
Ideal for combustion control in boilers, incinerators and furnaces.
Benefits
This oxygen analyser r can continuously measure the oxygen concentration in the non-combustible exhaust gases from industrial boilers or furnaces, and is suitable for combustion management and control. The system consists of a probe and a controller integrated into a complete unit. The probe includes the convection tube and the sensor. The convection tube, inserted into the flue, carries the sample gas to the sensor. The controller features a sensor diagnostic function and a recovery function, which ensure long-term reliability and measurement stability.
