Product Description
221L Disposable CO / Pentane / Oxygen (18% O₂) Calibration Gas for High-Volume Low-Oxygen Calibration
Built for extended-duration calibration in demanding environments, this 221L disposable calibration gas cylinder contains a precise blend of Carbon Monoxide (CO) 250 PPM, Pentane (C₅H₁₂) 0.35% (25% LEL), and Oxygen (O₂) 18.0%, balanced with nitrogen. Pressurized to 250 PSI, this non-reactive steel cylinder is ideal for pentane-based LEL calibration in oxygen-deficient conditions across large-scale operations.
