Product Description
120L CO 60 PPM / Pentane / Oxygen Calibration Gas (25% LEL, 19.0% O₂) for Extended Confined Space Calibration
This 120L calibration gas cylinder is designed for extended calibration use in oxygen-deficient environments, featuring a precise blend of Carbon Monoxide (CO) 60 PPM, Pentane (C₅H₁₂) 0.35% (25% LEL), and Oxygen (O₂) 19.0%, balanced with nitrogen. Pressurized to 1050 PSI, this non-reactive aluminum cylinder provides longer runtime and reduced replacement frequency, making it ideal for calibration of sensitive CO sensors in confined space safety programs.
