    Product Description

    High CO 4 Gas Calibration Gas – 120L Cylinder

    This large-volume four-gas calibration mixture supports ongoing detector maintenance where elevated carbon monoxide alarm setpoints must be validated alongside hydrogen sulfide and combustible channels under normal atmospheric oxygen.

    Designed for safety programs performing frequent bump testing or scheduled calibrations across multiple instruments.
