Product Description
120L 4-Gas Calibration Cylinder – 100 PPM H₂S with 12% Oxygen Deficiency Simulation
This high-capacity 4-gas calibration blend is engineered for large confined space programs requiring elevated hydrogen sulfide verification and severe oxygen-deficiency validation.
With oxygen reduced to 12.0%, this mixture confirms detector response in extreme atmospheric conditions where alarm reliability is critical to worker safety.
Gas Composition Profile
Hydrogen Sulfide (H₂S): 100 PPM
Carbon Monoxide (CO): 50 PPM
Methane (CH₄): 2.5% (50% LEL)
Oxygen (O₂): 12.0%
Balance Gas: Nitrogen
• 100 PPM H₂S validates higher toxic alarm thresholds.
• 50 PPM CO confirms mid-range carbon monoxide response accuracy.
• 2.5% methane equals 50% LEL for combustible channel verification.
• 12.0% oxygen simulates severe oxygen-deficient environments far below the 19.5% OSHA benchmark.
This blend enables full multi-channel validation across toxic, combustible, and oxygen sensors in a single calibration cycle.
