Product Description
15.0% Oxygen Calibration Gas – CO 60 PPM / CH₄ 2.5% (50% LEL) – 11L Cylinder
This 15.0% oxygen calibration gas is engineered for extreme oxygen-deficiency simulation, enabling immediate, on-demand validation of gas detectors in high-risk confined space and industrial environments.
The mixture includes Carbon Monoxide (CO) 60 PPM, supporting precision toxic gas calibration at lower thresholds, and Methane (CH₄) 2.5% (50% LEL) for high-level combustible gas response verification, ensuring detectors perform reliably under severe hazard conditions. Oxygen at 15.0% simulates extreme oxygen-deficient environments, well below safe atmospheric limits.
Supplied in an 11L aluminum cylinder at 140 PSI with a trigger valve, this disposable configuration provides controlled, instant gas release, allowing technicians to perform rapid bump testing with minimal setup.
