    Product Description

    221L Disposable 4 Gas Calibration Gas – CO, CH₄, O₂ (Extended Use Cylinder)

    This 221L disposable 4 gas calibration gas is designed for professionals who need longer-lasting calibration gas without transitioning to refillable cylinders. It delivers accurate concentrations of Carbon Monoxide (CO), Methane (CH₄), and Oxygen (O₂) balanced in nitrogen for reliable multi-gas detector calibration.

    With increased capacity over smaller disposable cylinders, this option is ideal for extended field operations, multi-day projects, and higher-frequency bump testing environments.

    Gas Composition

    • Carbon Monoxide (CO): 50 PPM
    • Methane (CH₄): 2.5% (50% LEL)
    • Oxygen (O₂): 20.9%
    • Balance Gas: Nitrogen (N₂)

    Cylinder Specifications

    • Cylinder Size: 221L
    • Pressure: 250 PSI
    • Valve: CGA-165
    • Material: Steel
    • Type: Disposable
    • Reactivity: Non-Reactive

    Applications

    • Extended field calibration work
    • Multi-day job site testing
    • High-frequency bump testing programs
    • Industrial safety and compliance
    • Confined space monitoring

    Why This 221L Disposable Cylinder Stands Out

    • Longer runtime than 34L disposables
    • Eliminates need for refillable cylinder handling
    • Ideal for remote or extended-duration jobs
    • Compatible with CGA-165 regulators
    • Reduces frequency of cylinder replacement in the field
