    Product Description

    680L High-Capacity 4-Gas Calibration Gas for CO, % CO₂ (2.0%), CH₄ (LEL), and O₂

    This 680L calibration gas cylinder is engineered for high-volume calibration environments, delivering a consistent gas mixture of Carbon Monoxide (CO) 25 PPM, Carbon Dioxide (CO₂) 2.0%, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 21.0% balanced in Nitrogen.

    The 2.0% CO₂ concentration (20,000 ppm) supports industrial-grade calibration scenarios, including confined space programs and environments requiring higher CO₂ range validation.

    680L Calibration Gas Cylinder Specifications – High-Volume Aluminum Cylinder

    • Cylinder Size: 680L
    • Cylinder Pressure: 1800 PSI
    • Cylinder Volume: 19 Cubic Feet
    • Valve Type: CGA Specific
    • Cylinder Material: Aluminum
    • Gas Reactivity: Non-Reactive
    • Blend Type: Custom Mix

    Built for Facility-Level Calibration & Large Detector Fleets

    • Centralized calibration for large safety programs
    • High-frequency detector calibration environments
    • Multi-unit gas detector maintenance programs
    • Industrial plants, refineries, utilities, and manufacturing sites
    • Long-duration calibration cycles with fewer cylinder changeouts

    Why 680L Cylinders Reduce Operational Cost

    High-capacity cylinders significantly lower cost per calibration, reduce cylinder handling frequency, and minimize downtime across large teams or multiple job sites.

    2.0% CO₂ Calibration for Elevated Detection Ranges

    Using percentage-level CO₂ (2.0%) ensures accurate response in higher concentration environments, where ppm-level calibration gases are not sufficient for compliance or process monitoring.

    Why Buyers Choose High-Capacity Calibration Gas

    • Fewer replacements → less operational interruption
    • Better for calibration labs and centralized maintenance teams
    • Optimized for long-term usage and procurement efficiency
    • Supports consistent calibration across multiple detectors

    Custom Calibration Gas Solutions

    We offer custom gas mixtures, alternate CO₂ concentrations, and cylinder sizes tailored to your specific detectors and compliance requirements.
