Product Description
Pentane Equivalent Calibration Gas – CO 60 PPM / CH₄ 1.45% (58% LEL) / O₂ 16.0% – 120L Cylinder
This multi-gas calibration mixture is designed for pentane-equivalent LEL calibration, supporting consistent and accurate validation of gas detectors in hydrocarbon-sensitive and confined space environments.
The blend includes Carbon Monoxide (CO) 60 PPM for precision toxic gas calibration and Methane (CH₄) 1.45% (58% LEL Pentane Equivalent) to simulate detector response aligned with pentane-equivalent combustible gas scaling. Oxygen at 16.0% represents severely reduced atmospheric conditions, enabling calibration under high-risk environments.
Supplied in a 120L aluminum cylinder at 1050 PSI with a C-10 valve, this configuration is optimized for structured calibration programs, providing sufficient runtime for repeated use without the operational burden of larger cylinders.
