    Product Description

    CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.0% Calibration Gas – 66L 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 slightly reduced oxygen environments while maintaining accurate multi-gas detector calibration. Supplied in a 66L aluminum cylinder at 1150 PSI with a C-10 valve, this mixture is ideal for precision calibration scenarios that go beyond standard atmospheric testing.

    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

    • Precision calibration slightly below ambient oxygen levels
    • Detector sensitivity validation
    • Intermediate calibration between baseline and reduced oxygen environments
    • Industrial hygiene and safety verification

    Why This Gas Blend

    • 100 PPM CO supports low-range toxic gas calibration
    • Methane at 50% LEL for combustible hazard simulation
    • 20.0% oxygen introduces slight environmental deviation from baseline
    • Ideal bridge between 20.9% baseline and lower oxygen validation tiers
