    Product Description

    66L Custom CO / Pentane / Oxygen Calibration Gas for Specialized LEL Applications

    Engineered for advanced calibration requirements, this 66L custom calibration gas cylinder features a precise blend of Carbon Monoxide (CO) 250 PPM, Pentane (C₅H₁₂) 0.35% (25% LEL), and Oxygen (O₂) 19.0%, balanced with nitrogen. Filled to 1150 PSI, this non-reactive aluminum cylinder is designed for applications requiring pentane-based LEL calibration, where standard methane or propane mixes are not suitable.

    Gas Mixture & Cylinder Specifications

    • Carbon Monoxide (CO): 250 PPM
    • Pentane (C₅H₁₂): 0.35% (25% LEL)
    • Oxygen (O₂): 19.0%
    • Balance Gas: Nitrogen
    • Cylinder Size: 66L (2.3 cu ft)
    • Pressure: 1150 PSI
    • Material: Aluminum
    • Valve: C-10
    • Reactivity: Non-Reactive

    Applications & Use Cases

    • Calibration of detectors requiring pentane-specific LEL response
    • Cross-sensitivity testing and validation
    • Industrial hygiene and process safety applications
    • Specialized environments where propane or methane are not accurate substitutes
    • Custom compliance or research-based calibration programs

    Why Buyers Choose This Custom Mix

    • Pentane-based LEL calibration for higher specificity
    • 25% LEL concentration for controlled calibration points
    • Higher CO concentration (250 PPM) for expanded sensor range testing
    • Custom-engineered blend not commonly available off-the-shelf
    • Ideal for engineers, specialists, and regulated environments
