Product Description
Pentane Equivalent Calibration Gas – CO 60 PPM / CH₄ 1.45% (58% LEL) / O₂ 16.0% – 66L Cylinder
This multi-gas calibration mixture is engineered for specialized LEL calibration using pentane-equivalent response, enabling accurate detector validation in environments where standard methane calibration does not fully represent real-world conditions.
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 calibrated against pentane-equivalent combustible gas scales. Oxygen at 16.0% represents severely reduced oxygen conditions, allowing calibration under high-risk atmospheric scenarios.
Supplied in a 66L aluminum cylinder at 1150 PSI with a C-10 valve, this configuration is optimized for operational calibration workflows requiring pentane-equivalent accuracy.
