Product Description
221L CO / Pentane / Oxygen Calibration Gas (50% LEL, 19.0% O₂) for Extended Oxygen-Deficiency Calibration
Designed for long-duration calibration in oxygen-deficient environments, this 221L calibration gas cylinder contains a precise blend of Carbon Monoxide (CO) 100 PPM, Pentane (C₅H₁₂) 0.75% (50% LEL), and Oxygen (O₂) 19.0%, balanced with nitrogen. Pressurized to 250 PSI, this non-reactive disposable steel cylinder is ideal for extended field use, multi-instrument calibration, and compliance-driven confined space programs without refill logistics.
