Product Description
120L CO / Pentane / Oxygen Calibration Gas (25% LEL, 20.9% O₂) for Extended Compliance Calibration
This 120L calibration gas cylinder is designed for extended-use calibration under normal atmospheric conditions, featuring 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 1050 PSI, this non-reactive disposable aluminum cylinder is ideal for multi-instrument calibration workflows, reduced replacement frequency, and consistent compliance testing.
