    Product Description

    66L 15.0% Oxygen Calibration Gas – Extreme Deficiency Simulation

    This 66 Liter reactive 4-gas calibration cylinder is formulated to simulate extreme oxygen-deficient environments at 15.0% O₂, significantly below OSHA’s 19.5% minimum safe threshold.

    At 15.0% oxygen, this blend creates a high-severity low-O₂ condition used for advanced alarm verification, emergency response preparation, and confined space rescue training scenarios.

    Gas Composition

    • Hydrogen Sulfide (H₂S): 10 PPM

    • Carbon Monoxide (CO): 50 PPM

    • Methane (CH₄): 2.5% (50% LEL)

    • Oxygen (O₂): 15.0%

    • Balance: Nitrogen

    This mixture allows simultaneous validation of oxygen, toxic, and combustible detection channels under aggressive deficiency conditions.

    Cylinder Configuration

    • Size: 66L

    • Pressure: 1150 PSI

    • Valve: C-10

    • Material: Aluminum

    • Gas Type: Reactive

    • Approximate Volume: 2.3 Cubic Feet

    The 1150 PSI fill pressure supports recurring training cycles while maintaining portable field usability.

    Intended Applications

    • Confined space rescue training

    • Emergency response drills

    • Advanced industrial safety programs

    • SCBA scenario validation

    • High-severity alarm testing

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

    Why Choose the 15.0% O₂ Blend

    • Simulates extreme oxygen-deficient environments
    • Confirms alarm activation under high-severity conditions
    • Tests multi-sensor performance in a single cycle
    • Reactive formulation engineered for stable sensor interaction

    Custom oxygen levels, PSI ratings, and alternate gas compositions available upon request.
