Product Description:
YJJ SO2/CF-2000 Electrochemical Sulfur-Dioxide Sensor 0-2000PPM Built-in Filter for Flue-gas Emission Monitor
Features:
I. Core Performance Parameters
Detected gas: Hydrogen Sulfide (H2S)
Standard measurement range: 0 - 2000 ppm
Instantaneous pressure overload upper limit: 4000 ppm
Sensing principle: Three-electrode electrochemical cell
Sensitivity: 50 ± 9 nA/ppm
T90 response time: < 35 s
Resolution: 2 ppm
Zero point range at 20°C clean air: -20 to +20 ppm
Zero drift within 20 - 40°C temperature range ≤ 4 ppm
Long-term drift: Monthly signal attenuation < 2%
Recommended load resistance: 10Ω, no electrode bias voltage required, simple peripheral circuit
II. Environmental Operating Specifications
Operating temperature: -40°C to +50°C, extremely wide low-temperature adaptability
Air pressure adaptation: Standard atmospheric pressure ±10%
Operating humidity: 15% - 90% RH, no condensation of water vapor
Average lifespan in air: 24 months
Sealed storage shelf life: 6 months
Physical specifications: Standard C-Series 4-pin cylindrical package, weight approximately 8g
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
