    Product Description

    CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.0% Calibration Gas – 221L Cylinder

    This calibration gas blend contains Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 20.0%, balanced in nitrogen to simulate controlled, slightly reduced oxygen environments. This enables accurate multi-gas detector calibration when validating performance beyond standard atmospheric 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 cycles across teams or sites
    • Standardized detector validation programs
    • Precision calibration with reduced operational interruptions
    • Industrial hygiene and compliance workflows

    Why This Gas Blend

    • 100 PPM CO supports low-range toxic gas calibration
    • Methane at 50% LEL for combustible hazard simulation
    • 20.0% oxygen provides controlled deviation from ambient conditions
    • Extended-use cylinder reduces downtime and improves workflow efficiency
