    Product Description

    34L CO (10 PPM), CH₄ (50% LEL), and O₂ Calibration Gas – Portable Low-Level CO Calibration

    This 34L custom calibration gas cylinder is designed for portable calibration and field use, supporting accurate low-level carbon monoxide detection alongside standard combustible gas testing.

    The mixture includes 10 PPM Carbon Monoxide (CO) for sensitive toxic gas calibration, 2.5% Methane (50% LEL) for standard LEL verification, and 20.9% Oxygen (O₂) to simulate normal atmospheric conditions.

    This blend is ideal for technicians performing on-site calibration of multi-gas detectors requiring precise low-range CO accuracy.
