Product Description
15.0% Oxygen Calibration Gas – CO 60 PPM / CH₄ 2.5% (50% LEL) – 116L Cylinder
This 15.0% oxygen calibration gas is engineered for extreme oxygen-deficiency simulation, supporting precise and repeatable validation of gas detectors in high-risk confined space and industrial environments.
The mixture includes Carbon Monoxide (CO) 60 PPM, enabling lower-threshold toxic gas calibration, and Methane (CH₄) 2.5% (50% LEL) for elevated 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 levels.
Supplied in a 116L aluminum cylinder at 1000 PSI with a C-10 valve, this configuration is designed for spec-controlled calibration programs, where exact cylinder size and pressure must be matched for compliance and operational consistency.
