Product Description
15.0% Oxygen Calibration Gas – CO 100 PPM / CH₄ 2.5% (50% LEL) – 680L Cylinder
This 15.0% oxygen calibration gas is engineered for extreme oxygen-deficiency validation, where gas detection systems must perform under the most severe and 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 severe 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 a 680 liter aluminum cylinder at 1800 PSI with a CGA-specific valve, this configuration is designed for continuous, high-volume calibration programs, minimizing downtime while supporting large-scale validation across multiple instruments and teams.
