Product Description
34L Disposable 4-Gas Calibration Cylinder – 100 PPM CO with 18% Oxygen
This disposable 4-gas calibration blend is designed for facilities operating conservative H₂S thresholds and standard carbon monoxide alarm setpoints while requiring controlled oxygen-deficiency validation.
With oxygen reduced to 18.0%, this cylinder confirms toxic, combustible, and oxygen channel performance under realistic confined-space alarm conditions.
Gas Composition Profile
Hydrogen Sulfide (H₂S): 15 PPM
Carbon Monoxide (CO): 100 PPM
Methane (CH₄): 2.5% (50% LEL)
Oxygen (O₂): 18.0%
Balance Gas: Nitrogen
• 15 PPM H₂S supports early toxic alarm verification.
• 100 PPM CO aligns with common industrial CO setpoints.
• 2.5% methane equals 50% LEL for combustible sensor calibration.
• 18.0% oxygen simulates deficiency below OSHA’s 19.5% benchmark.
This blend enables full multi-channel validation within a single servicing cycle.
