    Product Description

    H₂S 25 PPM / CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.9% 4-Gas Calibration Gas – 60L Cylinder

    This 4-gas calibration blend includes:

    • Hydrogen Sulfide (H₂S) – 25 PPM

    • Carbon Monoxide (CO) – 100 PPM

    • Methane (CH₄) – 2.5% (50% LEL)

    • Oxygen (O₂) – 20.9%

    • Balance Gas – Nitrogen

    Designed for routine calibration and bump testing of portable multi-gas detectors operating in standard atmospheric oxygen conditions.

    Gas Composition

    H₂S 25 PPM / CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.9%
    Balance: Nitrogen
    Gas Count: 4

    Cylinder Specifications

    Cylinder Size: 60L
    Valve Type: C-10
    Cylinder Material: Aluminum
    Gas Reactivity: Reactive

    Application Positioning

    This blend is ideal for:

    • Routine OSHA-required bump testing

    • Standard atmospheric verification

    • Confined space programs

    • Utility and municipal safety teams

    • Detector fleet maintenance

    With 20.9% oxygen, this mixture simulates normal ambient air conditions rather than oxygen-deficient alarm testing.

    Methane at 2.5% equals 50% LEL for proper combustible sensor verification.
    CO at 100 PPM aligns with common alarm calibration thresholds.

    Need Alternate Pressure or Cylinder Configuration?

    We manufacture this blend across multiple cylinder sizes and pressures. Contact us for alternate PSI ratings or custom gas concentrations.
