Product Description
44L 4-Gas Calibration Cylinder – 100 PPM H₂S with 12% Oxygen Deficiency
This 4-gas calibration blend is engineered for confined space programs requiring elevated hydrogen sulfide validation and deep oxygen-deficiency simulation in a portable format.
With oxygen reduced to 12.0%, this mixture confirms detector performance under severe atmospheric conditions where rapid alarm activation is critical.
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-level carbon monoxide response.
• 2.5% methane equals 50% LEL for combustible sensor calibration.
• 12.0% oxygen simulates severe oxygen-deficient environments well below the 19.5% OSHA benchmark.
This blend allows full multi-channel alarm verification during a single calibration cycle.
