    Product Description

    Portable Confined Space Calibration Gas – 44L Cylinder

    This reduced-oxygen calibration mixture verifies detector readiness where atmospheric safety cannot be assumed.
    The 19.0% oxygen concentration confirms deficiency alarm performance while toxic and combustible channels are validated at the same time.

    The compact 44L cylinder is commonly used by technicians carrying calibration gas into the field or between job sites.
