    Product Description

    CO 250 PPM / CH₄ 2.5% (50% LEL) / O₂ 18.0% Calibration Gas – 17L Cylinder

    This calibration gas blend contains Carbon Monoxide (CO) 250 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 18.0%, balanced in nitrogen to simulate reduced oxygen environments while maintaining accurate multi-gas detector calibration. Packaged in a 17L steel cylinder at 240 PSI with a CGA-600 valve, this disposable format is ideal for portable use and rapid field calibration.

    Cylinder & Mixture Details

    • Cylinder Size: 17L (0.6 Cubic Feet)
    • Cylinder Pressure: 240 PSI
    • Cylinder Material: Steel
    • Valve Type: CGA-600
    • Gas Reactivity: Non-Reactive
    • Balance Gas: Nitrogen (N₂)

    Applications & Use Cases

    • Portable gas detector bump testing
    • Field calibration in reduced oxygen environments
    • Confined space entry safety checks
    • Industrial hygiene spot monitoring

    Why This Gas Blend

    • 250 PPM CO supports mid-range toxic gas calibration
    • Methane at 50% LEL for combustible hazard simulation
    • Reduced oxygen level (18.0%) reflects real-world confined conditions
    • Ultra-portable cylinder for quick deployment and ease of use
