Product Description
60L 4-Gas Calibration Cylinder – 250 PPM CO with 18% Oxygen Deficiency Simulation
This 4-gas calibration blend is designed for facilities requiring elevated carbon monoxide validation combined with controlled oxygen-deficiency testing.
With CO at 250 PPM and oxygen reduced to 18.0%, this cylinder supports toxic, combustible, and oxygen channel verification under realistic confined space alarm conditions.
Gas Composition Profile
Hydrogen Sulfide (H₂S): 15 PPM
Carbon Monoxide (CO): 250 PPM
Methane (CH₄): 2.5% (50% LEL)
Oxygen (O₂): 18.0%
Balance Gas: Nitrogen
• 15 PPM H₂S confirms sensitive H₂S alarm programming.
• 250 PPM CO validates higher CO alarm thresholds.
• 2.5% methane equals 50% LEL for combustible sensor calibration.
• 18.0% oxygen simulates deficiency below OSHA’s 19.5% limit.
This combination enables full multi-channel stress validation in a single servicing cycle.
Cylinder Specifications
