Product Description
Pentane Equivalent Calibration Gas – CO 60 PPM / CH₄ 1.45% (58% LEL) / O₂ 15.0% – 17L
This multi-gas calibration gas is designed for pentane-equivalent LEL calibration, providing accurate detector response in hydrocarbon environments where methane-based calibration alone may not reflect real-world conditions.
The mixture includes Carbon Monoxide (CO) 60 PPM for toxic gas calibration, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent) for combustible gas response aligned to pentane scaling, and Oxygen (O₂) 15.0% to simulate extreme oxygen-deficient atmospheres.
Supplied in a 17L steel cylinder at 240 PSI with a CGA-600 valve, this disposable format supports portable calibration, bump testing, and pre-entry safety checks.
