    Product Description

    4 Gas H2S CO CH4 O2 Calibration Gas – 116L Cylinder

    This four-gas calibration mixture confirms detector response where reduced oxygen levels and lower carbon monoxide alarm thresholds must activate reliably. The 116L cylinder supports daily monitoring routes and multi-instrument verification while minimizing cylinder replacement frequency.

    What This Cylinder Verifies

    • Toxic gas detection at reduced CO alarm thresholds

    • Oxygen-deficiency alarm activation

    • Combustible gas response (methane LEL)

    Used when confirming detector sensitivity and readiness before entry into hazardous environments.

    Typical Applications

    • Confined space entry programs

    • Daily bump-testing routes

    • Industrial safety inspections

    • Wastewater monitoring

    • Preventative maintenance calibration

    Custom Mixtures Available

    Calibration blends available to match detector alarm setpoints and monitoring procedures.
