    Product Description

    34L CO, CH₄ (20% LEL), and O₂ Calibration Gas for Detector Calibration

    This 34L calibration gas cylinder is designed for routine calibration and bump testing of multi-gas detectors, providing a reliable balance between portability and usable gas volume.

    The mixture includes 1.0% Methane (20% LEL) for controlled combustible gas calibration and 20.9% Oxygen (O₂) to simulate normal atmospheric conditions. Paired with 50 PPM Carbon Monoxide (CO), this blend supports accurate sensor response verification across toxic, combustible, and oxygen channels.
