    Product Description

    34L Disposable 4-Gas Calibration Cylinder – 100 PPM CO, 20.9% O₂

    This 34L disposable reactive 4-gas calibration cylinder is engineered to verify 100 PPM carbon monoxide alarm thresholds while maintaining standard atmospheric oxygen at 20.9% O₂.

    Designed for quick bump testing and short-duration detector validation cycles.

    Gas Composition

    • Hydrogen Sulfide (H₂S): 10 PPM

    • Carbon Monoxide (CO): 100 PPM

    • Methane (CH₄): 2.5% (50% LEL)

    • Oxygen (O₂): 20.9%

    • Nitrogen: Balance

    The 100 PPM CO concentration confirms intermediate alarm response levels.
    The 20.9% oxygen baseline ensures realistic ambient-air calibration.

    Disposable Cylinder Specifications

    • Capacity: 34L

    • Fill Pressure: 500 PSI

    • Valve Type: C-10

    • Cylinder Material: Aluminum

    • Cylinder Type: Disposable

    • Gas Type: Reactive

    • Approximate Volume: 1.2 Cubic Feet

    The disposable configuration eliminates return logistics and simplifies calibration management for small teams.

    Ideal For
