Product Description
15.0% Oxygen Calibration Gas – CO 60 PPM / CH₄ 2.5% (50% LEL) – 221L Cylinder
This 15.0% oxygen calibration gas is engineered for extreme oxygen-deficiency simulation, supporting continuous and reliable validation of gas detectors in high-risk confined space and industrial environments.
The mixture includes Carbon Monoxide (CO) 60 PPM, enabling precision toxic gas calibration at lower thresholds, and Methane (CH₄) 2.5% (50% LEL) for elevated combustible gas response verification, ensuring detectors perform accurately under severe hazard conditions. Oxygen at 15.0% simulates extreme oxygen-deficient environments, well below safe atmospheric limits.
Supplied in a 221L steel cylinder at 250 PSI with a CGA-165 valve, this configuration is designed for extended calibration cycles, reducing the need for frequent cylinder changeouts while maintaining consistent performance validation.
