Product Description
34L Disposable 4-Gas Calibration Cylinder – 250 PPM CO with 18% Oxygen
This disposable 4-gas calibration blend is engineered for facilities requiring elevated carbon monoxide alarm validation combined with controlled oxygen-deficiency simulation.
With CO at 250 PPM and oxygen reduced to 18.0%, this cylinder confirms toxic, combustible, and oxygen sensor performance under demanding confined-space 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 verifies lower H₂S alarm sensitivity.
• 250 PPM CO validates elevated CO alarm setpoints.
• 2.5% methane equals 50% LEL for combustible channel calibration.
• 18.0% oxygen simulates deficiency below OSHA’s 19.5% benchmark.
This blend enables full multi-channel stress validation in a single bump or calibration cycle.
