Product Description
44L 4-Gas Calibration Cylinder – 250 PPM CO with 18% Oxygen Deficiency Simulation
This 4-gas calibration blend is configured for facilities requiring elevated carbon monoxide validation combined with controlled oxygen-deficiency alarm testing.
With CO at 250 PPM and oxygen reduced to 18.0%, this mixture verifies toxic, combustible, and oxygen channel performance under realistic 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 confirms lower H₂S alarm sensitivity.
• 250 PPM CO validates high-threshold CO alarm setpoints.
• 2.5% methane equals 50% LEL for combustible sensor calibration.
• 18.0% oxygen simulates a deficiency atmosphere below OSHA’s 19.5% limit.
This configuration allows technicians to stress CO response while verifying oxygen depletion alarms within the same calibration cycle.
