    Product Description

    CO 200 PPM / CH₄ 2.5% (50% LEL) / O₂ 18.0% Calibration Gas – 11L Cylinder

    This ultra-compact calibration gas blend contains Carbon Monoxide (CO) 200 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 18.0%, balanced in nitrogen to simulate reduced oxygen environments commonly encountered in confined spaces while maintaining accurate multi-gas detector calibration. Supplied in an 11L aluminum cylinder at 140 PSI with a trigger valve, this disposable configuration allows controlled gas release for efficient bump testing and mobile calibration.

    Cylinder & Mixture Details

    • Cylinder Size: 11L (0.4 Cubic Feet)
    • Cylinder Pressure: 140 PSI
    • Cylinder Material: Aluminum
    • Valve Type: Trigger Valve
    • Gas Reactivity: Non-Reactive
    • Balance Gas: Nitrogen (N₂)

    Applications & Use Cases

    • Rapid bump testing of portable gas detectors
    • Confined space entry safety calibration
    • Detector response validation in reduced oxygen environments
    • Mobile industrial hygiene monitoring

    Why This Gas Blend

    • 200 PPM CO supports lower-range toxic gas calibration
    • Methane at 50% LEL for combustible hazard simulation
    • 18.0% oxygen reflects real-world reduced oxygen conditions
    • Trigger valve enables controlled, efficient gas delivery
    • Ultra-portable cylinder for quick deployment
