Oxygen content in flue gases is the primary value that is used optimization of combustion processes in different facilities.
Major problems of reliable measurement of oxygen in flue gases are solved successfully by means of zirconium oxide based sensor *.
|
|
In addition to this sensor a catalytic detectors can be installed into the instrument to measure combustibles and/or methane as well.
We offer reliable analyzers capable of operation in wet dirty gases. All analyzers use probes and operate - as a rule - without sample handling systems.

* For power industry we offer non-explosion proof CEM LAND analyzers
