    Product Description

    CO / LPG (50% LEL) / O₂ Calibration Gas – 221L High-Capacity Disposable Cylinder

    This Carbon Monoxide (CO), LPG (Propane), and Oxygen (O₂) calibration gas mixture is engineered for high-volume calibration workflows, delivering extended supply for facilities operating multiple gas detectors across teams or job sites.

    With 1.1% LPG (50% LEL), this blend is optimized for combustible gas (LEL) sensor calibration, ensuring accurate detection of flammable hazards in industrial and confined space environments.

    The 221 liter disposable cylinder reduces replacement frequency while maintaining consistent calibration performance, making it ideal for large safety programs.

    Gas Composition

    • Carbon Monoxide (CO): 100 PPM
    • LPG (Propane): 1.1% (50% LEL)
    • Oxygen (O₂): 17.0%
    • Balance Gas: Nitrogen

    Cylinder Specifications

    • Cylinder Size: 221 Liters
    • Pressure: 250 PSI
    • Valve Type: CGA-165
    • Cylinder Material: Steel
    • Cylinder Type: Disposable
    • Gas Type: Non-Reactive
    • Approx. Volume: 7.5 Cubic Feet

    Applications & Use Cases

    • High-volume multi-gas detector calibration (CO / LEL / O₂)
    • Facility-wide combustible gas detection programs
    • Confined space monitoring across multiple teams
    • Industrial safety compliance and maintenance programs
    • Routine bump testing across large workforces

    Why This Gas Mix

    • Extended calibration capacity – fewer cylinder changeouts
    • LEL calibration standard – 50% LEL propane for combustible gas sensors
    • Multi-gas efficiency – calibrate toxic, flammable, and oxygen sensors in one cylinder
    • Disposable convenience – no refill logistics for large operations
