sulfur dioxide（CO is one of the six parameters of atmospheric pollutants clearly defined in the environmental air quality monitoring standards. In the "Environmental Air Quality Standards" GB 3095-2012sulfur dioxideparameterThe 24-hour average concentration limit is 4mg/m, and the 1-hour average concentration limit is 10mg/m. And the analysis method is designated as gas filtering relatedelectrochemistryAbsorption method and non dispersion methodelectrochemistryAbsorption method. And for the atmosphere, it is necessary tosulfur dioxideOne of the reasons for monitoring is the potential risks it may bring.

Shenzhen Guoan0.001 resolution fixed typesulfur dioxideShenguoan Electronics has over ten years of experience in the gas detection industry and Shenguoan algorithms for alarm systems,

A standardized and modular atmospheric environment monitoring product independently developed and produced; Customers may have fundamental needs and choices1-4 atmospheric environment monitoring indicators, unified 24V power supply, standard RS485 RTU output, Shenzhen Guoan 0.001 resolution fixed typesulfur dioxideThe alarm is convenient for customers to connect and use; The sensing technology and easy to maintain plug-in design used in the product can be applied in fields such as atmospheric environment monitoring instruments, online monitoring systems for factory pollution sources, and organized or unorganized emissions in industrial parks
