    Product Description

    680L 4 Gas Calibration Gas – 40% LEL Methane, CO, O₂ (Facility-Scale Cylinder)

    This 680L high-capacity 4 gas calibration gas is designed for large-scale multi-gas detector calibration under standard atmospheric conditions, featuring 50 PPM Carbon Monoxide (CO), 2.0% Methane (40% LEL), and 20.9% Oxygen (O₂) balanced in nitrogen.

    This mixture provides a 40% LEL methane concentration, allowing safety teams to perform controlled, lower-range LEL validation across multiple detectors and systems.

    Gas Composition

    • Carbon Monoxide (CO): 50 PPM (Standard Level)
    • Methane (CH₄): 2.0% (40% LEL)
    • Oxygen (O₂): 20.9% (Atmospheric Baseline)
    • Balance Gas: Nitrogen (N₂)

    Cylinder Specifications

    • Cylinder Size: 680L
    • Pressure: 1800 PSI
    • Valve: CGA (Application Specific)
    • Material: Aluminum
    • Reactivity: Non-Reactive

    Applications

    • Facility-wide LEL sensor calibration
    • Multi-detector system validation
    • Industrial safety compliance programs
    • Continuous calibration operations
    • Controlled methane response testing

    Why 40% LEL at Facility Scale Matters

    • Enables lower-range LEL validation across entire systems
    • Supports multi-point calibration strategies
    • Allows teams to test detectors under graduated LEL exposure levels
    • Reduces need for frequent cylinder replacement
    • Complements standard 50% LEL calibration programs

    40% vs 50% LEL Calibration

    • 50% LEL (2.5% CH₄) → standard calibration
    • 40% LEL (this SKU) → controlled, lower-range validation

    At this size, this becomes a program-level calibration tool, not just a product.

    Oxygen Context

    • 20.9% (this SKU) → baseline atmosphere
    • 19.0% → early deficiency
    • 18.0% → critical
    • 17.0% → severe

    Why 680L for Calibration Programs

    • Supports high-frequency, multi-device calibration
    • Minimizes downtime and cylinder changeouts
    • Ideal for centralized calibration systems
    • Designed for continuous operational use
