Description
Overview
GAOTek industrial flue gas analyzer core component is a zirconia sensor. Compared with similar products on the market, it has the characteristics of high measurement accuracy, short response time, wide measurement range, high use temperature, reliable operation, easy installation, and small maintenance. Therefore, it is widely used in metallurgy, chemical industry, electric power, heating, environmental protection and other industries to analyze the oxygen content of flue gas in various industrial boilers and kilns; the control of pollutants in medical waste incinerators; the control of pollution emissions by CEMS; the steel refining Application of furnace VOD.
