    Product Description

    High-Volume CO / Hydrogen / Oxygen Custom Calibration Gas for Field Operations

    This custom calibration gas mixture contains Carbon Monoxide (CO) 2.0%, Hydrogen (H₂) 2.0% (50% LEL), and Oxygen (O₂) 6.0%, balanced in nitrogen. Supplied in a 221L steel disposable cylinder at 250 PSI with a CGA-165 valve, this blend is engineered for high-usage calibration environments requiring reliable and consistent gas delivery.

    The larger disposable format allows for extended calibration cycles without frequent cylinder replacement, making it ideal for teams managing multiple detectors or ongoing calibration programs in the field.

    Gas Composition

    • Carbon Monoxide (CO): 2.0%
    • Hydrogen (H₂): 2.0% (50% LEL)
    • Oxygen (O₂): 6.0%
    • Balance Gas: Nitrogen

    Cylinder Specifications

    • Cylinder Size: 221L
    • Cylinder Pressure: 250 PSI
    • Cylinder Material: Steel
    • Valve Type: CGA-165
    • Cylinder Type: Disposable
    • Gas Reactivity: Non-Reactive

    Applications

    • Hydrogen (H₂) LEL sensor calibration in high-use environments
    • Multi-gas detector calibration across multiple units
    • Field-based safety and compliance programs
    • Routine bump testing and extended calibration cycles
    • Industrial operations requiring large-volume disposable gas supply

    Key Advantages

    • 221L disposable cylinder supports extended use without frequent changeouts
    • Hydrogen at 50% LEL enables accurate combustible gas response testing
    • Elevated CO and reduced oxygen simulate demanding detection conditions
    • Designed for efficient field deployment without permanent cylinder handling
    • Compatible with CGA-165 regulators and high-volume calibration setups

    Custom Calibration Gas Options

    Custom calibration gas mixtures are available for applications requiring different concentrations, cylinder sizes, or gas combinations.
