    Product Description

    CO / Hexane 25% LEL / O₂ 17% Multi-Gas Calibration Gas – 221L Disposable Cylinder

    This multi-gas calibration mixture contains Carbon Monoxide (CO) 50 ppm, Hexane (C₆H₁₄) 0.30% (25% LEL), and Oxygen (O₂) 17.0%, balanced with nitrogen. Supplied in a 221 liter steel cylinder at 250 PSI with a CGA-165 valve, this blend is non-reactive and packaged in a disposable cylinder for extended field use.

    Designed for multi-gas detector calibration, this mixture enables accurate verification of toxic gas (CO), combustible gas (LEL), and oxygen-deficiency sensors using a single, higher-capacity cylinder.

    Gas Composition

    • Carbon Monoxide (CO): 50 ppm
    • Hexane (C₆H₁₄): 0.30% (25% LEL)
    • Oxygen (O₂): 17.0%
    • Balance Gas: Nitrogen

    Cylinder Specifications

    • Cylinder Size: 221 Liters (7.5 Cubic Feet)
    • Cylinder Pressure: 250 PSI
    • Valve Type: CGA-165
    • Cylinder Material: Steel
    • Cylinder Type: Disposable
    • Gas Reactivity: Non-Reactive

    Applications & Compatibility

    • Calibration of portable and fixed multi-gas detectors
    • Oxygen-deficiency alarm verification (17% O₂)
    • LEL sensor calibration using hexane equivalency
    • Extended field calibration and maintenance programs
    • Industrial hygiene and confined space compliance testing

    Why This Calibration Gas

    • Higher-capacity disposable cylinder for longer calibration cycles
    • Reduces frequency of cylinder change in active field programs
    • Simulates real confined space atmospheric conditions
    • Combines CO + LEL + O₂ calibration in one solution
    • Stable, non-reactive blend for consistent performance
