Product Description
116L 4-Gas Calibration Cylinder – 250 PPM CO with 20.9% Ambient Oxygen
This 116L 4-gas calibration blend is engineered for facilities requiring elevated carbon monoxide alarm validation while maintaining stable ambient oxygen reference conditions.
With carbon monoxide at 250 PPM and methane at 50% LEL, this mixture confirms toxic and combustible sensor response across structured safety programs and centralized servicing environments.
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 validates low-to-moderate H₂S alarm sensitivity.
• 250 PPM CO supports high-threshold CO setpoint confirmation.
• 2.5% methane equals 50% LEL for combustible channel verification.
• 20.9% oxygen maintains atmospheric baseline reference.
This blend enables aggressive CO stress validation without introducing oxygen-deficiency simulation variables.
