III. Product Advantages
2000 ppm ultra-high measurement range, suitable for high-concentration hydrogen sulfide environments where ordinary sensors will saturate and fail
Strong low-temperature performance, zero drift is very small in extremely cold outdoor and underground low-temperature environments
Resistant to interference from impurity gases, suitable for complex mixed gases such as biogas and oilfield associated gas
Plug-and-play, compatible with common C-series sensor bases on the market
IV. Detailed Application Purposes
Oil and gas industry: Drilling platforms, oil and gas pipelines, refineries, gas collection stations for high-concentration hydrogen sulfide leakage monitoring
Biogas, anaerobic fermentation equipment: Biogas tanks, kitchen waste gas production equipment, biomass gas sulfur dioxide detection
Wastewater treatment plants, septic tanks, underground sewage pipelines for toxic gas monitoring
Mining, metal mining pit tunnels, avoiding the risk of high-concentration hydrogen sulfide outgassing from geological sources
Garbage landfill, livestock and poultry waste gas online monitoring
Fixed industrial gas alarm, OEM sensing probe for portable high-range gas analyzer
