    Product Description

    CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.0% Calibration Gas – 120L Cylinder

    This precision 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 slightly reduced oxygen environments while maintaining accurate multi-gas detector calibration. Supplied in a 120L aluminum cylinder at 1050 PSI with a C-10 valve, this mixture is ideal for calibration workflows that require consistent, repeatable validation beyond standard atmospheric conditions.

    Cylinder & Mixture Details

    • Cylinder Size: 120L (4.2 Cubic Feet)
    • Cylinder Pressure: 1050 PSI
    • Cylinder Material: Aluminum
    • Valve Type: C-10
    • Gas Reactivity: Non-Reactive
    • Balance Gas: Nitrogen (N₂)

    Applications & Use Cases

    • Precision calibration below ambient oxygen levels
    • Routine detector validation across controlled environments
    • Intermediate calibration between baseline and reduced oxygen tiers
    • Industrial hygiene and compliance programs

    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
    • High-demand cylinder size for consistent, repeat-use workflows
