Product Description
34L CO / Pentane / Oxygen Calibration Gas (25% LEL, 20.9% O₂) for Portable Compliance Calibration
This 34L calibration gas cylinder is designed for portable, routine calibration under normal atmospheric conditions, containing a precise blend of Carbon Monoxide (CO) 100 PPM, Pentane (C₅H₁₂) 0.375% (25% LEL), and Oxygen (O₂) 20.9%, balanced with nitrogen. Pressurized to 500 PSI, this non-reactive disposable steel cylinder is ideal for field technicians, low-volume calibration tasks, and compliance verification without the need for larger cylinders.
