    Product Description

    120L 4 Gas Calibration Gas – 12.0% O₂ Extreme Oxygen Deficiency (Field-Ready Cylinder)

    This 120L 4 gas calibration gas is engineered for extreme oxygen-deficiency simulation in field environments, featuring 12.0% Oxygen (O₂) alongside Carbon Monoxide (CO) and Methane (CH₄) balanced in nitrogen.

    Designed for real-world deployment, this cylinder allows technicians to validate gas detection systems under severely oxygen-depleted, emergency-level conditions, ensuring accurate alarm response in high-risk environments.

    Gas Composition

    • Carbon Monoxide (CO): 50 PPM
    • Methane (CH₄): 2.5% (50% LEL)
    • Oxygen (O₂): 12.0% (Extreme Deficiency Level)
    • Balance Gas: Nitrogen (N₂)

    Cylinder Specifications

    • Cylinder Size: 120L
    • Pressure: 1050 PSI
    • Valve: C-10
    • Material: Aluminum
    • Reactivity: Non-Reactive

    Applications

    • Emergency-level oxygen deficiency testing
    • Confined space worst-case validation
    • Multi-gas detector stress testing
    • Industrial safety compliance
    • Field-based high-risk calibration

    Why This 120L 12% O₂ Cylinder is the Practical Choice

    • Simulates extreme oxygen-deficient environments
    • More usable than bulk cylinders for on-site work
    • Provides longer runtime than smaller cylinders
    • Compatible with C-10 regulated calibration systems
    • Ideal for serious field validation programs

    Oxygen Calibration Severity Scale

    • 20.9% O₂ → baseline
    • 19.0% O₂ → early deficiency
    • 18.0% O₂ → critical threshold
    • 17.0% O₂ → severe deficiency
    • 12.0% O₂ (this SKU) → extreme / emergency-level validation

    120L vs Other Extreme O₂ Options

    • 60L → portable extreme testing
    • 120L (this SKU) → optimal field deployment
    • 680L → facility-scale systems
