Description
The gas zirconia oxygen analyzer is suitable for continuous monitoring of the oxygen content in the flue gas produced by combustion equipment such as boilers and heating furnaces during the combustion process. Meanwhile, the gas zirconia oxygen analyzer can quickly and accurately display, detect, and analyze online to achieve low-oxygen combustion control, achieve energy saving and reduce environmental pollution.
Application
The gas zirconia analyzers are widely used energy-consuming industries, such as iron and steel, electric power, oil and petrochemical, ceramics, pulp and paper, food, and textiles, to various combustion facilities, such as incinerators and small- and medium sized boilers.
Main Features
★ Easy Operation Easy to operate by functional key.
★ Easily replaceable zirconia element.
★ IP66 or IP67 enclosure.
★ Fast response.
★ Withstand the pressure of ±8KPa.
