Product Description
221L CO 60 PPM / Pentane / Oxygen Calibration Gas (25% LEL, 19.0% O₂) for Low-Pressure Confined Space Calibration Systems
This 221L calibration gas cylinder is designed for low-range CO calibration in confined space environments, featuring a precise mixture of Carbon Monoxide (CO) 60 PPM, Pentane (C₅H₁₂) 0.35% (25% LEL), and Oxygen (O₂) 19.0%, balanced with nitrogen. Pressurized to 250 PSI, this non-reactive disposable steel cylinder is ideal for applications requiring low-pressure delivery, CGA-165 regulator compatibility, and accurate calibration of sensitive CO sensors.
