Product Description
66L CO (10 PPM), CH₄ (50% LEL), and O₂ Calibration Gas – Low-Level CO Detection + Standard LEL Testing
This 66L custom calibration gas cylinder is designed for applications requiring low-level carbon monoxide calibration alongside standard combustible gas testing.
The mixture includes 10 PPM Carbon Monoxide (CO) for sensitive toxic gas calibration, 2.5% Methane (50% LEL) for combustible gas response testing, and 20.9% Oxygen (O₂) to simulate normal atmospheric conditions.
This combination is ideal for multi-gas detectors that require accurate low-range CO calibration while maintaining standard LEL verification.
