Product Description
221L CO 60 PPM / Pentane / Oxygen Calibration Gas (25% LEL, 15.0% O₂) for Low-Pressure Severe Oxygen Deficiency Testing
This 221L calibration gas cylinder is designed for low-range CO calibration in severely oxygen-deficient environments, featuring a precise mixture of Carbon Monoxide (CO) 60 PPM, Pentane (C₅H₁₂) 0.35% (25% LEL), and Oxygen (O₂) 15.0%, balanced with nitrogen. Pressurized to 250 PSI, this non-reactive disposable steel cylinder is ideal for low-pressure delivery systems, CGA-165 regulator compatibility, and validation of detector performance under extreme confined space conditions.
