Product description: Air pollution monitoring device for civil air defense engineering, designed for real-time monitoring of safety hazards in tunnels, underground passages, basements, subways, sports venues, large supermarkets, new and old residential area renovations, kindergartens, parks, hospitals and other public places in civil air defense construction. This alarm device has the advantages of long lifespan, good stability, strong anti-interference ability, small size, light weight, and simple and convenient installation. At the same time, it has digital display and sound and light alarm functions, prompting safety warnings within the area and effectively protecting the safety of personnel in enclosed spaces. Monitoring gas classification: It can be selected to detect conventional toxic gases such as hydrogen sulfide, ammonia, carbon monoxide, etc. It can also be selected to detect other chemical toxic gases (chemical agents and their compounds containing sulfur and phosphorus elements), as well as other toxic gases (sulfur, phosphorus compounds, Lewis gas, mustard gas, phosgene, sarin, sulfur dioxide, sulfur dioxide, hydrogen sulfide, ammonia, hydrogen cyanide, formaldehyde, ozone, nitrogen monoxide, nitrogen dioxide, tetrahydrothiophene and other toxic gases). It can also be selected to detect other common toxic gases such as carbon dioxide, carbon monoxide, sulfur dioxide, chlorine gas, hydrogen sulfide, ammonia, hydrogen cyanide, formaldehyde, ozone, nitrogen monoxide, nitrogen dioxide, tetrahydrothiophene and so on Monitoring occasions: all occasions that require portable and rapid detection of gas concentration, such as civil defense engineering, petroleum, chemical, pharmaceutical, environmental protection, gas distribution, warehousing, smoke analysis, air treatment, etc Monitoring principles: electrochemistry, catalytic combustion, infrared, thermal conductivity, PID photoionization, etc., depending on gas type, range, on-site environment, and user requirements. Can be used in conjunction with FGB04 toxic agent alarm probe, and can be used in conjunction with oral toxic agent probe. Real time measurement of radiation in Y and X radiation workplaces can be achieved; It can achieve independent setting of alarm thresholds for each probe; Capable of storing and accessing alarm records; Comes with a built-in optocoupler relay output; Comes with a built-in sound and light alarm output; Can achieve network communication with the control host and upper computer monitoring system; Provide 485 interface and MODBUS protocol.
