    Product Description

    High-Volume CO / Hydrogen / Oxygen (1.0%) Custom Calibration Gas for Extreme Field Calibration

    This custom calibration gas mixture contains Carbon Monoxide (CO) 800 PPM, Hydrogen (H₂) 800 PPM, and Oxygen (O₂) 1.0%, 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 precise low-level gas detection and near-anoxic simulation.

    The large disposable format supports extended calibration cycles without frequent cylinder replacement, making it ideal for field teams managing multiple detectors or conducting continuous safety validation in high-risk environments.

    Gas Composition

    • Carbon Monoxide (CO): 800 PPM
    • Hydrogen (H₂): 800 PPM
    • Oxygen (O₂): 1.0%
    • 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

    • Extreme oxygen-deficiency sensor calibration at scale
    • Low-level CO sensor calibration across multiple detectors
    • Hydrogen (H₂) sensor verification at ppm detection levels
    • Confined space testing under near-anoxic conditions
    • Field-based industrial safety and compliance programs

    Key Advantages

    • 221L disposable cylinder reduces frequency of changeouts
    • 1.0% oxygen enables near-anoxic environment simulation
    • 800 PPM concentrations provide precise low-range calibration
    • Designed for efficient deployment in field calibration operations
    • Compatible with CGA-165 regulators and high-volume calibration setups

    Custom Calibration Gas Options

    Custom calibration gas mixtures are available for applications requiring alternative concentration ranges, cylinder sizes, or gas combinations.
