Product Description
15.0% Oxygen Calibration Gas – CO 100 PPM / CH₄ 2.5% (50% LEL) – 11L Cylinder
This 15.0% oxygen calibration gas is engineered for severe oxygen-deficiency validation, where gas detection systems must perform reliably under extreme, high-risk conditions.
The mixture includes Carbon Monoxide (CO) 100 PPM for toxic gas calibration and Methane (CH₄) 2.5% (50% LEL) for combustible gas response verification. Oxygen at 15.0% simulates extreme oxygen-deficiency environments beyond critical safety thresholds, enabling accurate validation of multi-gas detectors used in confined space entry, industrial hygiene, and emergency response operations.
Supplied in an 11 liter aluminum cylinder at 140 PSI with a trigger valve, this disposable configuration allows controlled, on-demand gas release, making it ideal for rapid bump testing and immediate pre-entry validation in severe oxygen-deficiency conditions.
