    Product Description

    34L Disposable 4-Gas Calibration Gas – 35 PPM CO with 18.0% O₂

    This 34L disposable reactive 4-gas calibration cylinder is engineered for facilities validating 35 PPM carbon monoxide alarm thresholds, supporting early-warning CO programs while simultaneously confirming oxygen and LEL channel performance.

    The 18.0% oxygen concentration creates a controlled oxygen-deficient environment below OSHA’s 19.5% threshold, enabling realistic confined space simulation.

    Gas Blend

    • Hydrogen Sulfide (H₂S): 10 PPM

    • Carbon Monoxide (CO): 35 PPM

    • Methane (CH₄): 2.5% (50% LEL)

    • Oxygen (O₂): 18.0%

    • Nitrogen: Balance

    This configuration validates oxygen, toxic, and combustible detection channels in portable multi-gas monitors.

    Disposable Cylinder Specifications

    • Capacity: 34L

    • Fill Pressure: 500 PSI

    • Valve Type: C-10

    • Cylinder Material: Aluminum

    • Cylinder Type: Disposable

    • Gas Type: Reactive

    • Approximate Volume: 1.2 Cubic Feet

    The disposable format eliminates return handling and simplifies logistics for short-term projects and contractor calibration kits.

    Typical Applications

    • Confined space contractor programs

    • Early-warning CO threshold calibration

    • Industrial hygiene spot checks

    • Safety training kits

    • Temporary job site detector validation

    Compatible with standard C-10 demand flow regulators used across major portable gas detection platforms.

    Why Choose the 35 PPM CO Disposable Blend

    • Supports lower CO alarm setpoint validation
    • Compact and transport-friendly format
    • Confirms O₂ and LEL response simultaneously
    • Disposable design simplifies program management

    Custom CO concentrations and alternate oxygen percentages available upon request.
