    Product Description

    CO 250 PPM / CH₄ 2.5% (50% LEL) / O₂ 18.0% Calibration Gas – 66L Cylinder

    This calibration gas mixture contains Carbon Monoxide (CO) 250 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 18.0%, balanced in nitrogen to support accurate gas detector calibration in reduced oxygen environments. Supplied in a 66L aluminum cylinder at 1150 PSI with a C-10 valve, this blend is designed for applications requiring both combustible gas simulation and controlled oxygen conditions.

    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

    • Multi-gas detector calibration and bump testing
    • Confined space monitoring with reduced oxygen conditions
    • Industrial hygiene compliance and safety verification
    • Detector response testing under controlled atmospheric conditions

    Why This Gas Blend

    • 250 PPM CO for mid-range toxic gas calibration
    • Methane at 50% LEL for combustible gas simulation
    • Reduced oxygen level (18.0%) for realistic confined environment calibration
    • Stable output for consistent and repeatable detector performance
