In the development of modern society, there are more and more kinds of toxic gases, especially the majority of factories. In the industrial development, it is inevitable that there will be leakage of toxic gases. If effective measures are not taken for these gases in a timely manner, it will cause a very bad impact. Therefore, it is very necessary to configure toxic gas detector for many industries.

Application in refining and chemical industry: refining and chemical industry mainly includes crude oil separation, heavy oil lightening, oil upgrading and refining, oil blending equipment, gas processing equipment, hydrogen production, chemical product production and many other processing processes. What gases will be formed in this series of production and processing? That is, what kind of toxic gas is detected by the toxic gas detector used in the refining industry? The toxic gases formed in the refining process are mainly hydrogen sulfide, sulfur dioxide and carbon monoxide. Therefore, the toxic gas detector mainly includes hydrogen sulfide detector, sulfur dioxide detector and carbon monoxide detector.

Application in the iron and steel industry: Industrial gas is generally used as fuel in iron and steel smelting. Since blast furnace gas, converter gas and coke oven gas with high carbon monoxide content are involved, the gas detector in iron and steel smelting mainly detects carbon monoxide, which can also be called carbon monoxide detector.
