    Product Description

    44L Portable 4-Gas Calibration Gas – 100 PPM CO with 20.9% O₂

    This 44L reactive 4-gas calibration cylinder is designed to verify 100 PPM carbon monoxide alarm setpoints while maintaining normal atmospheric oxygen at 20.9% O₂.

    Its compact size and 750 PSI fill make it well-suited for mobile technicians and field-based compliance checks.

    Gas Blend

    • Hydrogen Sulfide (H₂S): 10 PPM

    • Carbon Monoxide (CO): 100 PPM

    • Methane (CH₄): 2.5% (50% LEL)

    • Oxygen (O₂): 20.9%

    • Nitrogen: Balance

    The 100 PPM CO concentration validates mid-range toxic alarm response.
    The 20.9% oxygen level mirrors real-world ambient air conditions.

    Cylinder Specifications

    • Capacity: 44L

    • Fill Pressure: 750 PSI

    • Valve Type: C-10

    • Cylinder Material: Aluminum

    • Gas Type: Reactive

    • Approximate Volume: 1.5 Cubic Feet

    The 750 PSI configuration provides stable regulator flow for efficient bump testing and alarm verification cycles.
