    Product Description

    CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 19.0% Calibration Gas – 221L Cylinder

    This calibration gas blend contains Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 19.0%, balanced in nitrogen to simulate moderately reduced oxygen environments. This allows for accurate multi-gas detector calibration when validating performance under real-world operating conditions. Supplied in a 221L steel cylinder at 250 PSI with a CGA-165 valve, this configuration is ideal for extended calibration cycles and reduced cylinder changeout frequency.

    Cylinder & Mixture Details

    • Cylinder Size: 221L (7.5 Cubic Feet)
    • Cylinder Pressure: 250 PSI
    • Cylinder Material: Steel
    • Valve Type: CGA-165
    • Gas Reactivity: Non-Reactive
    • Balance Gas: Nitrogen (N₂)

    Applications & Use Cases

    • Extended calibration programs in reduced oxygen environments
    • Confined space compliance testing
    • Multi-unit detector validation workflows
    • Industrial hygiene and safety programs

    Why This Gas Blend

    • 100 PPM CO supports low-range toxic gas calibration
    • Methane at 50% LEL for combustible hazard simulation
    • 19.0% oxygen simulates moderate oxygen deficiency
    • Larger cylinder reduces downtime and improves workflow efficiency
