    Product Description

    120L 4 Gas Calibration Gas – CO, CH₄, O₂ (Balanced Performance Cylinder)

    This 120L 4 gas calibration mixture provides the ideal balance between portability and extended usage, making it a preferred choice for technicians performing routine calibration and bump testing in the field.

    With Carbon Monoxide (CO), Methane (CH₄), and Oxygen (O₂) balanced in nitrogen, this gas blend delivers reliable accuracy for multi-gas detector calibration across industrial, safety, and compliance applications.

    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: 120L
    • Pressure: 1050 PSI
    • Valve: C-10
    • Material: Aluminum
    • Reactivity: Non-Reactive

    Applications

    • Daily gas detector calibration
    • Field service and technician use
    • Confined space entry preparation
    • Industrial safety programs
    • Maintenance and compliance testing

    Why This 120L Cylinder Stands Out

    • More capacity than 60L without sacrificing portability
    • Ideal for routine field calibration schedules
    • Reduces frequency of cylinder replacement
    • Lightweight aluminum for easy handling
    • Standard C-10 compatibility for quick integration
