Product Description
CO 50 ppm / Pentane 0.14% (10% LEL) / Oxygen 18.0% Calibration Gas – 221L Disposable Cylinder
This extended-capacity disposable calibration gas cylinder is designed for field calibration of gas detection systems at ultra-low combustible gas thresholds across high-demand environments. Featuring Carbon Monoxide (CO) at 50 ppm, Pentane (C₅H₁₂) at 10% LEL, and Oxygen (O₂) at 18.0%, it enables accurate validation of detector sensitivity across toxic, combustible, and oxygen monitoring channels.
The 221L capacity supports longer calibration cycles across teams and multiple devices, reducing cylinder replacement frequency in active field operations.
