    Product Description

    34L Disposable 4-Gas Calibration Gas – LPG Equivalent LEL with 19.0% O₂

    This 34L disposable reactive 4-gas calibration cylinder is designed for confined space gas detector calibration and bump testing where oxygen-deficiency conditions and LPG-equivalent combustible gas levels must be verified.

    The mixture contains 25 PPM hydrogen sulfide, 50 PPM carbon monoxide, 1.62% methane representing 50% LEL propane equivalent, and 19.0% oxygen, simulating hazardous atmospheric conditions commonly encountered in confined space environments.

    Gas Composition

    • Hydrogen Sulfide (H₂S): 25 PPM

    • Carbon Monoxide (CO): 50 PPM

    • Methane (CH₄): 1.62% (50% LEL LPG / Propane Equivalent)

    • Oxygen (O₂): 19.0%

    • Nitrogen: Balance

    The 19.0% oxygen concentration allows accurate verification of oxygen-deficiency alarms used in confined space safety monitoring programs.

    Cylinder Specifications

    • Capacity: 34L

    • Fill Pressure: 500 PSI

    • Valve Type: C-10

    • Cylinder Material: Aluminum

    • Cylinder Type: Disposable

    • Gas Type: Reactive

    • Approximate Volume: 1.2 Cubic Feet

    The disposable format eliminates return logistics and provides a convenient solution for short-duration calibration programs.

    Typical Applications

    • Confined space entry safety checks

    • Portable gas detector bump testing

    • Contractor safety kits

    • Industrial safety inspections

    • Field service calibration programs

    Compatible with C-10 demand flow regulators used across most portable multi-gas detectors.

    Why Choose This Disposable Calibration Blend

    • Simulates oxygen-deficient confined space atmospheres
    • Verifies LPG-equivalent combustible gas alarms
    • Confirms toxic gas sensor response (H₂S and CO)
    • Disposable cylinder simplifies field operations

    Custom calibration mixtures and alternate gas concentrations are available upon request.
