    Product Description

    60L 4-Gas Calibration Gas – 35 PPM CO with 18.0% O₂

    This 60L reactive 4-gas calibration cylinder is engineered for facilities that validate 35 PPM Carbon Monoxide alarm thresholds while simultaneously testing oxygen-deficiency and LEL response.

    Unlike standard 50 PPM CO blends, this configuration supports lower first-alarm setpoints commonly used in industrial hygiene and confined space programs.

    Gas Composition

    • Hydrogen Sulfide (H₂S): 10 PPM

    • Carbon Monoxide (CO): 35 PPM

    • Methane (CH₄): 2.5% (50% LEL)

    • Oxygen (O₂): 18.0%

    • Nitrogen: Balance

    The 18.0% oxygen level creates a controlled oxygen-deficient condition below OSHA’s 19.5% threshold, allowing comprehensive multi-sensor validation.

    Cylinder Specifications

    • Capacity: 60L

    • Fill Pressure: 1000 PSI

    • Valve Type: C-10

    • Cylinder Material: Aluminum

    • Gas Type: Reactive

    • Approximate Volume: 2.1 Cubic Feet

    The 1000 PSI fill pressure supports predictable regulator performance during scheduled calibration intervals.

    Designed For

    • Industrial hygiene compliance programs

    • Confined space entry teams

    • Manufacturing plant maintenance

    • Oil & gas monitoring systems

    • Utility safety departments

    Compatible with standard C-10 demand flow regulators used with major portable multi-gas detection systems.

    Why This 35 PPM CO Configuration

    • Supports lower CO alarm setpoint validation
    • Simultaneously verifies O₂ and LEL response
    • Balanced volume for recurring compliance schedules
    • Reactive blend engineered for stable detector output

    Custom CO concentrations and alternate oxygen percentages available upon request.
