Underground pipe gallery is the urban "lifeline" that integrates various pipelines such as electricity, communication, gas, water supply and drainage. The interior is in a sealed, humid, and poorly ventilated environment for a long time, which is prone to accumulationInsufficient methane, hydrogen sulfide, carbon monoxide, and oxygenDangerous gases, once leaked or lacking oxygen, may cause major accidents such as poisoning, explosion, suffocation, etc. Shenzhen Guoan Online Multi in One Gas Detector relies onMulti gas synchronous monitoring, real-time warning, strong environmental adaptabilityTo become the "core guardian" of gas safety management in pipeline corridors.

Multi gas full coverage, precise identification of pipe gallery risks

The risk of underground pipe gallery is complex: gas pipeline leakage occursMethane (flammable and explosive)Production of humic substances from sewage pipelinesHydrogen sulfide (highly toxic)Aging of electrical equipment may releaseCarbon monoxide (toxic)Insufficient ventilation can also lead toDecreased oxygen concentration (hypoxia asphyxia)The Shenzhen Ando integrated detector canSimultaneously monitor six or more gases including CH ₄, H ₂ S, CO, O ₂, VOCs, etcOne device covers all key risk factors in the pipeline gallery, avoiding blind spots of single gas detection and making hidden risks clearly visible.

Real time online monitoring, second level response to prevent accidents

Pipe corridors are often narrow and enclosed spaces, with rapid gas diffusion and sudden hazards. The Shenzhen Guoan detector adoptsImported high-precision sensorsThe methane detection accuracy reaches 0.1% LEL, the hydrogen sulfide is as low as 0.1ppm, and the response time is less than 3 seconds. Once the gas concentration exceeds the standard or oxygen is insufficient, it will be triggered immediatelyaudible and visual alarmSynchronize the linkage of the pipe gallery ventilation system, emergency lighting, and personnel positioning devices, and upload real-time data to the monitoring center through 4G/fiber optics. Management personnel can remotely assess, dispatch, and handle the situation, and prevent accidents from arising.
