    Product Description

    4 Gas H2S CO CH4 O2 Calibration Gas – 44L Cylinder

    This four-gas calibration mixture is designed to confirm detector response where reduced oxygen and lower carbon monoxide alarm thresholds must activate reliably. The compact 44L cylinder supports routine bump testing and safety verification without excess cylinder handling.

    What This Cylinder Verifies

    • Toxic gas detection at reduced CO alarm levels

    • Oxygen-deficiency alarm activation

    • Combustible gas detection (methane LEL)

    Used when validating alarm sensitivity before entry into hazardous environments.

    Typical Applications

    • Confined space entry checks

    • Portable bump testing kits

    • Alarm threshold verification

    • Industrial monitoring inspections

    • Routine maintenance calibration

    Custom Mixtures Available

    Calibration blends can be produced to match detector alarm setpoints and monitoring programs.
