    Product Description

    11L 4 Gas Calibration Gas – 12.0% O₂ Extreme Deficiency (Instant Trigger Valve)

    This 11L disposable 4 gas calibration gas is designed for immediate extreme oxygen-deficiency simulation, featuring 12.0% Oxygen (O₂) alongside Carbon Monoxide (CO) and Methane (CH₄) balanced in nitrogen.

    Equipped with a trigger valve, this cylinder allows for instant gas release without a regulator, making it ideal for technicians who need fast, reliable validation under emergency-level oxygen conditions.

    Gas Composition

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

    Cylinder Specifications

    • Cylinder Size: 11L
    • Pressure: 140 PSI
    • Valve: Trigger Valve (No Regulator Required)
    • Material: Aluminum
    • Type: Disposable
    • Reactivity: Non-Reactive

    Applications

    • Rapid extreme-condition validation
    • Emergency response readiness testing
    • Confined space pre-entry checks
    • Quick bump testing under severe conditions
    • Field-based safety verification

    Why This 11L 12% O₂ Cylinder is Critical

    • Simulates worst-case oxygen-deficient environments instantly
    • No regulator required — fastest deployment
    • Ultra-portable for field technicians
    • Ideal for high-urgency safety checks
    • Eliminates setup time in critical scenarios

    Trigger Valve vs Regulated Cylinders

    • Trigger valve (this SKU) → instant, no setup
    • CGA-600 / C-10 → controlled, regulated flow

    This SKU is for speed and simplicity, not precision flow control.

    Oxygen Severity Context

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

    Need Controlled Flow or Larger Capacity?

    We offer regulated cylinders and larger sizes for extended or precision calibration. Contact us for custom solutions.
