Description：
The explosion-proof zirconia oxygen analyzer not only is a practical and reliable automatic analytical instrument and also the explosion-proof zirconia oxygen analyzer has the characteristics of high sensitivity, good reproducibility and stability, wide range, automatic switching, fast response and continuous online measurement. Therefore, the Explosion-proof Zirconia Oxygen Analyzer can quickly and correctly detect and analyze the flue gas content generated by combustion equipment such as boilers, kiln and heating furnaces that to achieve low-oxygen combustion control, to achieve energy-saving purposes, reduce environmental pollution.
Application
The explosion-proof zirconia oxygen analyzer is mainly used in: coal-fired power plants, waste incineration power plants, biomass power plants, sulfuric acid plants, chemical plant boilers, hazardous waste treatment boilers, heating station boilers, steel plants, steel mills, petroleum Pipeline pressure station boilers and other fields.
Main Features
★ No special ground wire required.
★ High accuracy and wide range ratio.
★ Zirconia probe wear resistance and corrosion resistance.
★ Strong resistance to field interference.
★ Easy to install, the response is fast and widely used.
★ Convenient replacement of components, easy maintenance, and reduced use cost.
