Product Description
CO 250 PPM / CH₄ 2.5% (50% LEL) / O₂ 18.0% Calibration Gas – 120L Cylinder
This multi-gas calibration blend features Carbon Monoxide (CO) 250 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 18.0%, balanced in nitrogen to simulate reduced oxygen conditions while maintaining accurate combustible and toxic gas calibration. Supplied in a 120L aluminum cylinder at 1050 PSI with a C-10 valve, this mixture is designed for consistent performance in industrial and confined environment applications.
