Product Description
66L 4-Gas Calibration Cylinder – 100 PPM H₂S with 12% Oxygen Deficiency
This high-intensity 4-gas calibration blend is engineered for facilities requiring elevated hydrogen sulfide validation and deep oxygen-deficiency simulation.
With oxygen reduced to 12.0%, this mixture confirms detector response under severe atmospheric conditions typically associated with confined space emergencies.
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 high toxic alarm setpoints.
• 50 PPM CO confirms mid-level CO detection accuracy.
• 2.5% methane equals 50% LEL for combustible channel calibration.
• 12.0% oxygen simulates severe oxygen-deficient environments.
This configuration is used when detectors must demonstrate reliable response in high-risk atmospheric scenarios.
