High-temperature zirconia oxygen measurement
Fields of application
Biomass, oil, coal boiler/ Incinerator
Benefits
The Fuji Electric ZFKH in situ zirconia O₂ probe is suitable for installation in safe areas and for withstanding critical environments and high process gas temperatures. Coupled with the ZKM controller, it constitutes the high-temperature zirconia oxygenanalyser .
