    Product Description

    44L 18.0% Oxygen Deficiency Calibration Gas – Severe Low-O₂ Validation

    For confined space programs requiring deeper alarm verification margins, this 44L 4-gas blend at 18.0% O₂ provides controlled severe oxygen-deficiency simulation.

    Gas Mixture

    • Hydrogen Sulfide (H₂S) – 10 PPM

    • Carbon Monoxide (CO) – 50 PPM

    • Methane (CH₄) – 2.5% (50% LEL)

    • Oxygen (O₂) – 18.0%

    • Nitrogen – Balance

    At 18.0% oxygen, this blend creates a measurable deficiency condition well below OSHA’s 19.5% minimum, enabling confirmation of alarm activation and sensor stability across O₂, toxic, and combustible channels.

    Cylinder Details

    • Size: 44L

    • Pressure: 750 PSI

    • Valve: C-10

    • Material: Aluminum

    • Gas Type: Reactive

    • Approximate Volume: 1.5 Cubic Feet

    The 750 PSI configuration offers controlled output for technicians operating in field or contractor environments.

    Ideal For

    • Contractor confined space entry

    • Mobile compliance programs

    • Alarm setpoint verification

    • Industrial hygiene spot checks

    • Oil & gas maintenance crews

    Compatible with standard C-10 demand flow regulators and most major portable gas detectors.

    Why This 44L 18.0% Blend

    • Simulates severe oxygen-deficient environments
    • Confirms alarm activation below OSHA threshold
    • Compact size for mobile safety teams
    • Reactive mixture engineered for stable sensor interaction

    Custom oxygen percentages, PSI levels, and alternate gas ratios available upon request.
