    Product Description

    66L 4 Gas Calibration Gas – 12.0% O₂ Extreme Oxygen Deficiency Simulation

    This 66L 4 gas calibration gas is engineered for extreme oxygen-deficiency testing, featuring 12.0% Oxygen (O₂) alongside Carbon Monoxide (CO) and Methane (CH₄) balanced in nitrogen.

    At this concentration, the mixture enables validation of gas detection systems under severely oxygen-depleted conditions, making it suitable for emergency scenario simulation and advanced safety testing protocols.

    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: 66L
    • Pressure: 1150 PSI
    • Valve: C-10
    • Material: Aluminum
    • Reactivity: Non-Reactive

    Applications

    • Extreme oxygen deficiency calibration
    • Emergency response validation
    • Confined space worst-case simulation
    • Multi-gas detector stress testing
    • Industrial safety system verification

    Why 12.0% O₂ Calibration is Critical

    • Simulates severely oxygen-deficient environments
    • Validates detector performance under extreme conditions
    • Ensures alarms activate in worst-case scenarios
    • Supports high-level safety and compliance testing
    • Used for advanced and specialized calibration protocols

    Oxygen Calibration Severity Scale

    • 20.9% O₂ → normal atmospheric 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

    66L Cylinder Advantage

    • Portable enough for field deployment
    • Provides extended runtime vs smaller cylinders
    • Compatible with C-10 regulated calibration systems
    • Ideal for high-risk environment testing
