Product Description
34L Disposable 4-Gas Calibration Cylinder – 250 PPM CO with Ambient Oxygen
This disposable 4-gas calibration blend is configured for elevated carbon monoxide alarm validation while maintaining a 20.9% ambient oxygen reference.
With CO at 250 PPM and methane at 50% LEL, this cylinder supports robust toxic and combustible channel testing without introducing oxygen displacement conditions.
Gas Composition Profile
Hydrogen Sulfide (H₂S): 15 PPM
Carbon Monoxide (CO): 250 PPM
Methane (CH₄): 2.5% (50% LEL)
Oxygen (O₂): 20.9%
Balance Gas: Nitrogen
• 15 PPM H₂S confirms low-to-moderate H₂S alarm sensitivity.
• 250 PPM CO validates higher CO alarm thresholds.
• 2.5% methane equals 50% LEL for combustible sensor calibration.
• 20.9% oxygen maintains atmospheric reference conditions.
This configuration allows targeted CO stress validation while preserving oxygen channel stability.
