Product Description
CO 50 ppm / Pentane 0.35% (25% LEL) / Oxygen 12.0% Calibration Gas – 221L Disposable Cylinder
This extended-capacity disposable calibration gas cylinder is designed for multi-gas detector calibration in severely oxygen-deficient environments across high-demand field operations. Featuring Carbon Monoxide (CO), Pentane (C₅H₁₂) at 25% LEL, and reduced Oxygen (O₂) at 12.0%, it enables accurate validation of detector performance under extreme atmospheric conditions.
