    Product Description

    CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.9% Calibration Gas – 66L Cylinder

    This calibration gas blend contains Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 20.9%, balanced in nitrogen to replicate normal atmospheric conditions for accurate multi-gas detector calibration. Supplied in a 66L aluminum cylinder at 1150 PSI with a C-10 valve, this mixture is ideal for standard calibration procedures across industrial and safety applications.

    Cylinder & Mixture Details

    • Cylinder Size: 66L (2.3 Cubic Feet)
    • Cylinder Pressure: 1150 PSI
    • Cylinder Material: Aluminum
    • Valve Type: C-10
    • Gas Reactivity: Non-Reactive
    • Balance Gas: Nitrogen (N₂)

    Applications & Use Cases

    • Standard atmospheric calibration
    • Routine gas detector maintenance
    • Baseline sensor response verification
    • Industrial hygiene and safety compliance

    Why This Gas Blend

    • 100 PPM CO supports lower detection threshold calibration
    • Methane at 50% LEL for combustible hazard simulation
    • 20.9% oxygen replicates ambient atmospheric conditions
    • Ideal baseline gas before reduced-oxygen calibration scenarios
