Product Description:
YJJ DceL H2S 0-100ppm Electrochemical Hydrogen Sulfide Gas Sensor Portable Gas Detectors
Features:
I. Basic Information
Model: DceL-H2S (Ultra-thin, low-profile 3-pin electrochemical sensor, compatible with 4-series sensor size, thickness halved)
Detected gas: Hydrogen Sulfide (a highly toxic, rotten egg-like gas)
Principle: Three-electrode electrochemical principle, 0V bias, no power supply required
Positioning: Industrial-grade portable / fixed detection instrument dedicated, ultra-thin volume, high stability, anti-methanol interference
II. Core technical parameters (mainstream 0-100ppm version)
Measurement range: 0-100 ppm (also available 0-300ppm version)
Maximum overload: 200 ppm
Sensitivity output: 140±30 nA/ppm
Baseline drift: ±2ppm H₂S equivalent in clean air
Response time: T90 < 30 seconds
Resolution: < 0.1 ppm (depending on the backend circuit)
Repeatability: < ±2%FS
Recommended load resistance: 10Ω
Operating temperature: -30℃ ~ +50℃

Pressure range: 800 - 1200 mbar
Life & Warranty: Expected lifespan 24 months, original factory warranty 24 months
Core advantages: Low cross-interference with methanol, temperature drift resistance, rapid recovery, strong environmental adaptability
Pin: 3 pins, ultra-thin, low-profile packaging, compatible with 4-series sensor mechanical size
III. Main applications (compatible with your existing sensor procurement system)
Petrochemical / Oil and Gas Extraction: Oil fields, drilling platforms, refineries, natural gas pipelines H₂S leakage detection
Wastewater Treatment / Municipal: Sewage plants, septic tanks, garbage stations, underground pipelines sulfur dioxide monitoring, to prevent poisoning and explosion
Mining and Metallurgy: Coal mines, non-ferrous metal mines underground toxic gas inspection
Portable gas detector: Can directly replace H₂S sensors of brands such as METTLER TOLEDO, SENKO
Fixed gas alarm: Online monitoring in industrial plants, chemical workshops
Livestock / Biogas Industry: Biogas tanks, livestock farms sulfur dioxide concentration detection
Limited space operations: Enclosed tanks, cellars, pipeline maintenance before safety inspection
