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.
