    Product Description

    120L 4-Gas Calibration Gas – 200 PPM CO with 20.9% Oxygen

    This 120L reactive 4-gas calibration cylinder supports large-scale validation of 200 PPM carbon monoxide alarm thresholds while maintaining standard atmospheric oxygen at 20.9% O₂.

    Designed for centralized safety programs and high-volume detector maintenance environments.

    Gas Mixture

    • Hydrogen Sulfide (H₂S): 10 PPM

    • Carbon Monoxide (CO): 200 PPM

    • Methane (CH₄): 2.5% (50% LEL)

    • Oxygen (O₂): 20.9%

    • Nitrogen: Balance

    The 200 PPM CO concentration confirms upper alarm activation without introducing oxygen-deficiency variables.
    The 20.9% oxygen level reflects normal ambient air conditions.

    High-Capacity Cylinder Specifications

    • Capacity: 120L

    • Fill Pressure: 1050 PSI

    • Valve Type: C-10

    • Cylinder Material: Aluminum

    • Gas Type: Reactive

    • Approximate Volume: 4.2 Cubic Feet

    The 1050 PSI fill supports extended calibration cycles and reduces downtime from frequent cylinder swaps.

    Ideal For

    • Enterprise confined space compliance

    • Manufacturing plant safety divisions

    • Oil & gas production facilities

    • Utility and energy fleets

    • Multi-site detector standardization

    Compatible with C-10 demand flow regulators used across major portable 4-gas monitors.

    Why Choose the 120L 200 PPM Configuration

    • Supports fleet-wide CO alarm validation
    • Maintains atmospheric oxygen balance
    • Reduces cylinder change frequency
    • Engineered for consistent detector performance

    Custom CO setpoints and alternate oxygen percentages available upon request.
