    Product Description

    High-Volume CO / Hydrogen / Oxygen (2.0%) Custom Calibration Gas for Field Calibration Programs

    This custom calibration gas mixture contains Carbon Monoxide (CO) 800 PPM, Hydrogen (H₂) 800 PPM, and Oxygen (O₂) 2.0%, balanced in nitrogen. Supplied in a 221L steel disposable cylinder at 250 PSI with a CGA-165 valve, this blend is designed for high-usage calibration environments requiring precise low-level gas detection and extreme oxygen-deficiency simulation.

    The large disposable format supports extended calibration cycles without frequent cylinder replacement, making it ideal for teams managing multiple detectors or continuous field calibration operations.

    Gas Composition

    • Carbon Monoxide (CO): 800 PPM
    • Hydrogen (H₂): 800 PPM
    • Oxygen (O₂): 2.0%
    • 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

    • High-volume calibration of low-level CO sensors
    • Hydrogen (H₂) sensor verification at ppm detection levels
    • Oxygen-deficiency sensor testing in extreme low-O₂ environments
    • Field-based safety and compliance programs
    • Multi-detector calibration requiring extended gas supply

    Key Advantages

    • 221L disposable cylinder reduces frequency of changeouts
    • 800 PPM concentrations enable precise low-range calibration
    • 2.0% oxygen supports extreme oxygen-deficiency simulation
    • Designed for efficient deployment in field calibration operations
    • Compatible with CGA-165 regulators and high-volume calibration setups
