High-temperature zirconia oxygen measurement
Fields of application
Biomass, oil, coal boiler/ Incinerator
Benefits
The Fuji Electric ZFKH in-situ zirconia O₂ probe is designed for installation in safe areas and is capable of withstanding harsh environments and the high temperatures of process gases. When paired with the ZKM controller, it forms the high-temperature zirconia oxygenanalyser .
